Function f(x) is represented on the graph. Which statement identifies the effect of replacing f(x) with 1/2f(x) on the graph? A)The curve would remain the same size but would be flipped upside down. B)The curve would remain the same size but would shift to the left. C)The curve would be narrower, but the vertex would be in the same position. D)The curve would be wider, but the vertex would be in the same position.

Answers

Answer:

Option (D)

Step-by-step explanation:

If a function f(x) is represented on a graph and we follow the transformation as,

f(x) → $k.f(x)$

1). If k ≥ 1, graph of the parent function f(x) will be stretched vertically by a factor k.

That means the transformed graph will be narrower.

2). If 0 < k < 1, graph will be vertically compressed or the transformed function will show a wider graph.

Following this rule,

f(x) → $(1)/(2).f(x)$ shows k = $(1)/(2)$ [Since 0 < $(1)/(2)$ < 1]

Therefore, transformed form will be wider.

Option (D) will be the answer.

How to add and subtract fractions

Answers

You need to find the common denominator of all of the fraction and you also have to do whatever you did to the bottom to the top. So if you times the bottom by 2 you need to times the top by two. Then once you have that you can add and subtract!

You need to find the common denominator.

In your question :

4 2/7 - 2 1/5
= 4/1 * 2/7 - 2/1 * 1/5
= 8/7 - 2/5 ⇒ There, the common denominator is 7 * 5 = 35
= (8*5)/(7*5) - (2*7)/(5*7)
= 40/35 - 14/35
= (40-14)/35
= 26/35

The height of a ball when it is thrown into the air is shown by equation h = −16t2 + 20t + 3, where h is the height of the ball and t is time in seconds since the ball was released.A or B?
A.
linear model
B.
nonlinear model

Answers

From

h = -16t² + 20t + 3

This is a quadratic equation, it is degree 2 equation.

A degree 1 equation is a linear equation or model.

Any degree greater than 1, as 2 is a non linear.

So h = -16t² + 20t + 3, is a non linear model.

It is B.

I hope this helped.

Hello,

a quadratic equation is not a linear model.

Simplify. your answer should contain only positive exponents y^2x^3y^2
