Question

i already asked how to find the vertex but know i need to find the x and y intercepts to x^2+8x+7

Answer 1

set the equation equal to zero and you will find the x intercept(s)

Answer 2

unfoil the equation

Answer 3

(x+1)(x+7)=0

Answer 4

solve for x so x+1=0 and x+7=0

Answer 5

-7 -1

Answer 6

then x= -1 and x= -7

Answer 7

exactly

Answer 8

is that all you have to do to solve for x and y?

Answer 9

for the x intercept yes, but the y intercept you set the x values to zero and solve

Answer 10

ok

Answer 11

0^2 + 8(0) + 7 = y

Answer 12

thus y=7 and this is your y-intercept
