Given the function f(x) = -4x² + 7x, find f(5).

Answers

Answer 1
Answer:

Answer:

f(5) = -65

Step-by-step explanation:

f(x) = -4x² + 7x                                     f(5)

f(5) = -4(5)² + 7(5)

f(5) = -4(25) + 35

f(5) = -100 + 35

f(5) = -65

avocados cost $3 per pound. write and graph an equation in two variables that represents the cost of buying avocados

Answers

pounds will be represented by x and the cost will be represented by y. The equation is Y=3x. For the graph just use substition for x and then calculate the outcome and graph it.

if you horizontally shift the square root parent function, F(x) = √(x), left four units, what is the equation of the new function?

Answers

ANSWER

g(x) = √(x + 4)

EXPLANATION

The parent square root function is

f(x) = √(x)

The translation

g(x ) = √(x + k)

Will shift the graph of f(x) k units to left.

The translation

g(x) = √(x -k)

will shift the graph of f(x) to the right by k units.

Therefore if f(x) is shifted 4 units to the left its new equation is:

g(x) = √(x + 4)

Final answer:

Shifting a function left involves adding a value to the x-component. Hence, shifting the square root parent function, F(x) = √x, to the left by 4 units results in a new function F(x) = √(x+4).

Explanation:

When a function is shifted horizontally, it impacts the input or the x-values. A shift to the left is represented by the addition of a value to the x-component of the function. Hence, to shift the square root parent function, F(x) = √x, to the left by 4 units, you would add 4 to 'x' in the function, which results in a new function F(x) = √(x+4). "This function represents the original square root parent function shifted 4 units to the left".
