What would be two points of the parabloa other than the vertex and x-intercepts of r(x)=x^2+5x+4

Question

What would the other two points?

Answer 1

Hi, Tanearria. Try x = 1. Remember r(x) is the same as y, so let's re-write this as

 

y = x² + 5x + 4 = 1 + 5 + 4 = 10

 

So one point is (1, 10)

 

What about x = 2?

 

y = 2² + 5(2) + 4 = 4 + 10 + 4 = 18

 

Another point is (2, 18)
