f(x)=7-7x3+5x-x5-6x4
What is the y-intercept of the polynomial f(x) defined below? Write the y-value only.
Answer = 7
To find the Y-intercept, first put in standard form, and then replace all the x's with 0's.
f(x) = { (x+5)2 +3 for x < -3
{ -1 for x = -3
{ -2x - 1 for x >-3 (-1 is here)
Answer = 1 or f(-1) = -2(-1) -2 = 1
