Question

Which function could be shown in the attached graph?

A. f(x)=x^5-3x^2+2x
B. f(x)=4x^3-12x^2-x+15
C. f(x)=x^4-5x^2+4
D. f(x)=-3x^4+x^2-5

Answer 1

You will notice the curve crosses the y axis at y = -5. On the y axis x = 0. So which function gives you f(x) = -5 when x = 0?

Answer 2

I thought so! I got D & it was correct! thank you :)
