Find two points on the graph of the parabola other than the vertex and x-intercepts.

Question

r(x)=x²+8x+15

A: (_____,_____)

B: (_____,_____)

Answer 1

(0,15)

(1,24)

Just pick any simple number for x and plug it into the equation

r(0) = 0^2 + 8(0) + 15 = 15, that's the point (0,15) which is the y-intercept

r(1) = 1^2 + 8(1) +15 = 1+8+15 = 24. for the point (1,24)
