We know that when a line intercepts the y axis, x is 0. So substitute x as 0, which makes the equation 5y = 20 and divide both sides by 5, so y = 4 which is the y intercept.

Step-by-step explanation:
g(x)=ax²+3x-5
then g(-1)=-15
therefore g(-1) ⇒ a(-1)²+3(-1)-5=-15
a-3-5=-15
a-8=-15
a=-15+8
a=-7
for g(-1)=-15
then g(x)= -7x²+3x-5
If u end up with the exact same function that you started with (that is, if f (−x) = f (x), so all of the signs are the same), then the function is even if u end up with the exact opposite of what you started with (that is, if f (−x) = −f (x), so all of the signs are switched) then the function is odd
