Sketch the following polynomial function using the fourstep

Sketch the following polynomial function using the four-step process. f(x) = - x^5 + 2x^4 + 4x^3 - 8x^2 The left-hand behavior starts up and the right-hand behavior ends down Find the y-intercept. The y-intercept is Enter your answer box in the answer box and then click Check Answer.

Solution

f(x)=-x⁵+2x⁴+4x³-8x²

To find the y intercept we have to plug x=0

f(x)=0+2*0+4*0-8*0=0

Therefore y intercept is (0,0)
