Answer:

f(-2) = - 1

Step-by-step explanation:

f(n) = 4n^3 + 8n^2 - n - 3

f(-2) = 4(-2)^3 + 8(-2)^2 - (-2) - 3

f(-2) = 4(-8) + 8(4) + 2 - 3

f(-2) = -32+ 32 + 2 - 3

f(-2) = -1

What is the equation of the midline for the function f(x) ? f(x)=1/2sin(x)+6

Studentka2010 [4]

The midline is the y value that runs straight through the middle of the wave.If you can picture the standard sine function graph. f(x) = Sin(x) reaches a maximum y = 1 and minimum y = -1 so the midline is y =0.

This equation is shifted up 6 so the midline is shifted up 6
y = 6 is equation for midline
