Question

what are the x and y intercepts of the graph y=2x^2-8x-10

Answer 1

just set y to zero for the y intercept

Answer 2

ok now what do i do for the x's just plug stuff in?

Answer 3

oh i mean, y to zero for x intercept

Answer 4

then you just solve for x

Answer 5

that will be your x intercept

Answer 6

i dont get what you mean

Answer 7

at x=0, y =-10

Answer 8

i will let the others explain it

Answer 9

im still confused

Answer 10

i thought others would answer...

Answer 11

to find out the intercept of y, you set x to 0 and vice versa

Answer 12

understand?

Answer 13

yeah

Answer 14

step 2: when you set x to 0, you solve for y

Answer 15

do this

Answer 16

umm i got -187...

Answer 17

i think i did it wrong....

Answer 18

y=2x^2-8x-10

Answer 19

another way you could do this is by typing the equation into your calculator. When you graph the function, you can press 2nd Graph on your ti84 and scroll down to where x=0, you will see at x=0, y= -10 (check this by plugging in 0 to your equation for x. Likewise if you scroll down the table to y =0, you will see that x =5

Answer 20

i will let rogersmith take over

Answer 21

ok i dont know how i did this but i wrote down the wrong problem when i went to solve... my bad

Answer 22

ok then, i hope you found the solution!

Answer 23

ok for y i got -10

Answer 24

i got what to do for y now how do i do that for x

Answer 25

to find out the intercept of y, you set x to 0 and vice versa

Answer 26

nevermind i figured it out

Answer 27

well done
