Question

how do you find the x-intercept or zero's of f(x)=(x-5)(2x+3)

Answer 1

find for what values of x f(x)=0

Answer 2

Set both "parenthesis" equal to zero and solve.
So:
x-5=0
and
2x+3=0.
Solve for both and you have your answer

Answer 3

then how do you find the y intercept for f(x)=2x-10

Answer 4

believe it or not its actually -10. Why? this function is in the form of y=mx+b... where m is the slope and b is the y-intercept

Answer 5

well how do you solve it?

Answer 6

you dont. if you are just trying to find the y-intercept. then your answer is just -10. y-intercept is where the graph passes the y-axis. and it does so where y=-10

Answer 7

oh ha ok thanks
