Question

What is the y-intercept for the parabolax^2+ 5x - 24= 0

Answer 1

-24

Step-by-step explanation

The y-intercept is the value of y where the graph of the function intersects the y-axis. This always happens when x = 0, so to find it we have to replace x with 0 in the equation,

`y_(intercept)=0^2+5\cdot0-24=0+0-24=-24`

Hence, the y-intercept is -24.
