Question

The second one ^

What is the y-intercept for the quadratic
Y=4x^2 + 5x - 7?

Answer 1

-7

Explanation:

Since you are trying to solve for y, you set all the x values to 0.

(Y intercept occurs when x = 0, thats why you sub 0 for all x)

y= -4(0)^2
`y=-4(0)^(2) +5(0) -7`

this simplifies to

y=-7

Answer 2
