find the y-interept

Question

what is the y-intercept for the graph of this equation? y=-2.5x^2-24x-11

Answer 1

y = -2.5x² - 24x - 11

 

They-intercept is the point where the

graph crosses the y-axis.  This is where

the value of x is zero.  Simply set x=0

in the polynomial and solve for y.

 

y = -2.5(0²) - 24(0) - 11 = -11

 

 

The y-intercept is the point (0,-11)
