Answer:

Step-by-step explanation:

The easiest way to do this is two factor the equations or use the quadratic formula to find the roots if factoring is not possible. This way you can see which parabola each equation represents. Or you can find the vertex of each equation using -b/2a to determine which parabola corresponds to each equation.

Use synthetic division to solve (x4 – 1) ÷ (x – 1). What is the quotient?

Evaluate the function for x = –4c if c = –2.
irga5000 [103]
<span>x = –4c
</span>if c = -2 then x = -4(-2) = 8

I believed you  had a typo, function should be f(x) = -3x^2 - 4x 
so
<span>f(x) = -3x^2 - 4x 
</span>f(x) = -3(8^2) - 4(8)
f(x) = -3(64) - 32
f(x) = -192 - 32
f(x) = -224

answer

<span>C.
–224</span>
