Answer:

The correct answer is 2.

Step-by-step explanation:

Given y is directly proportional to x raised to the power n.

⇒ y \alpha x^{n}

⇒ y = p × x^{n} with p being the constant of proportion.

Let y be the area of a square of side x meters.

Therefore y = x^{2} square meters.

Now according to the given problem, comparing both the above mentioned equation we get the value of n equal to 2.

Given the function f(x) = -2x2 + 4x - 7, find f(-4).<br> -55<br> -7<br> 25
Neko [114]

Answer:

f(-4)= -55

Step-by-step explanation:

We want to find f(x), or y, when x is equal to -4.

Therefore, we can substitute -4 in for x in the function.

f(x) = -2x^2 + 4x - 7

Substitute -4 in for x

f(-4) = -2(-4^2) + 4(-4) - 7

Evaluate the exponent

f(-4)=-2(16)+4(-4)-7

Multiply -2 and 16

f(-4)= -32+4(-4)-7

Multiply 4 and -4

f(-4)=-32-16-7

Subtract

f(-4)=-55
