the function g(x) is a transformation of the quadratic parent function, f(x) = x^2. What function is g(x)

Answers

Answer:

Option (C)

Step-by-step explanation:

Quadratic parent function has been given as,

f(x) = x²

If we reflect this function across the x-axis and vertically stretched by a scale factor of 'k',

g(x) = -kx²

This quadratic function passes through a point (1, -4),

g(1) = -k(1)²

-4 = -k

k = 4

Therefore, the new function after transformation will be,

g(x) = -4x²

Option (C) will be the correct option.

The function g(x) is $\rm g(x) = -4x^2\n$ .

Given that,

The function g(x) is a transformation of the quadratic parent function,

$\rm f(x) = x^2$

We have to determine,

What function is g(x)?

According to the question,

The function f(x) is a transformation of the quadratic parent function,

$\rm f(x) = x^2$

In the given figure the function g(x) reflect across the x-axis and is vertically stretched by a scale factor of 'k',

Then, The function g(x) is,

$\rm g(x) = -kx^2$

Therefore,

The quadratic equation passes through the point (1,4),

$\rm g(x) = -kx^2\n\ng(1) = -k(1)^2\n\n-4 = -k\n\nk= 4$

Therefore,

The function g(x) is,

$\rm g(x) = -kx^2\n\ng(x) = -4x^2$

Hence, The required function g(x) is $\rm g(x) = -4x^2\n$ .

You earn $420 per week. You pay social security taxes of 7.65%, federal taxes of 22%, and state taxes of 5.95%. What is your take home pay?

Answers

Given:
weekly pay : 420 per week
social security tax rate : 7.65%
federal taxes : 22%
state taxes: 5.95%

All these tax rates are applied to the weekly earnings.

social security tax : 420 x 7.65% = 32.13
federal tax : 420 x 22% = 92.40
state tax : 420 x 5.95% = 24.99

420 - 32.13 - 92.40 - 24.99 = 270.48 take home pay.

We stared with $420 so..... 420-7.65% = $387.88Then subtract 22% from $387.78 which give you $302.53And last subtract 5.95% from $302.53 which give us the answer $284.52So you will be taking home $284.52I hope you understand and I hope my help is not a waste of time !

What is the only solution of 2x2 + 8x = x2 – 16

Answers

If you would like to solve the equation 2 * x^2 + 8 * x = x^2 - 16, you can calculate this using the following steps:

2 * x^2 + 8 * x = x^2 - 16
2 * x^2 - x^2 + 8 * x + 16 = 0
x^2 + 8 * x + 16 = 0
(x + 4) * (x + 4) = 0
x = - 4

The correct result would be x = - 4.

Answer:

x = -4 is the only solution.

Step-by-step explanation:

The given equation is 2x² + 8x = x² - 16

We can find the value of x by solving the equation.

(2x² + 8x) - x² = (x² - 16) - x²

x² + 8x = - 16

(x² + 8x) + 16 = (-16) + 16

x² + 8x + 16 = 0

(x + 4)² = 0 [ Since a² + b² + 2ab = (a + b)²]

⇒ (x + 4) = 0

x = -4

Therefore, x = -4 is the only solution of the given equation.

What is the equation of a line that is perpendicular to a line with a slope of 2 and passesthrough the point (-2, 0)?

Answers

To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3

Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.

y=3x+b

2=3*(3)+b

2=9+b

-7=b So now we know the y-intercept and slope. We just put them together now

y=3x-7
