For which equation will f(-2)= -6?

Mila [183]

Answer:

C. $f(x)=4x^3+6x^2-x$

Step-by-step explanation:

Lets plug in -2 into each of these equation to see which one gives us the solution of -6

A. $f(x)=x^3+x$

$f(-2)=(-2)^3+(-2)\\\\f(-2)=-8-2\\\\f(-2)=-10$

B. $f(x)=x^4-5x$

$f(-2)=(-2)^4-5(-2)\\\\f(-2)=16+10\\\\f(-2)=26$

C. $f(x)=4x^3+6x^2-x$

$f(-2)=4(-2)^3+6(-2)^2-(-2) \\\\f(-2)=4(-8)+6(4)+2\\\\f(-2)=-32+24+2\\\\f(-2)=-6$

D. $f(x)=-3x^3-4x^2+4x$

$f(-2)=-3(-2)^3-4(-2)^2+4(-2)\\\\f(-2)=-3(-8)-4(4)-8\\\\f(-2)=24-16-8\\\\f(-2)=0$

As we can see, function C was the only one that gave us the value of -6, so that is our answer.
