At what values of x, does f(x)=0
a. -4
b. 0
c. 4
d. 2
e. -1
f. 8

Options C, D, E are correct.

Step-by-step explanation:

See the graph shown in the attached file with the question.

It is clear from the graph that it touches the y-axis at three different points.  

So, there will be three different values of x for which f(x) = 0

And those values of x are - 1, 2, 4

Therefore, options C, D, E are correct. ( Answer )

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the answer is 1/4
