Question

Find the y intercept of the graph of this equation y = 5xsquared + 6x + 1

Answer 1

y-intercept: when x=0

y=5(0)^2+6(0)+1

what does that give you?

Answer 2

y=1

Answer 3

Yep, so your y intercept is (0,1)

Answer 4

1) The only thing you have to do to find out the y-intercept of this quadratic eqaution is look at the c term (the number without any variable attached to it)

2) That is your y-intercept so it would be (0,1) ... this works for every parabola

Hope that helps :D
