Find the y-coordinate of the y-intercept of the polynomial function defined
below.
f(x) = 9x^2 – 7 – 8x

Answer :

The y intercept is where the function passes through the y axis, so the “x” value needs to equal 0. We sub 0 in for “x” and solve for “y”.

f(0) = 9(0)^2 - 7 - 8(0)

f(0) = -7

Therefore the “y” coordinate would be -7

The ordered pair would be

(0, -7)
