Question

A polynomial function can be written as (x - 2)(x - 3)(x + 5). What are the x-intercepts of the graph of this function?

Answer 1

I think it is (-2, 0), (-3, 0), (5, 0)

Answer 2

the x-intercept occurs when y = 0
in order for y to be zero then one of the factors must be zero
set each factor = 0 and solve for x
the intercepts will be (x, 0) for each value of x

Answer 3

so was I right @triciaal ?

Answer 4

no but you were somewhat on the right track
(x-2) = 0 then x = 2

Answer 5

mind explaining it more? :P

Answer 6

you just don't pick up the numbers given

Answer 7

read the post slower , I already explained

Answer 8

ah ok.... then could it be (2, 0), (3, 0), (-5, 0)?

Answer 9

in order for y to be zero then one of the factors must be zero set each factor = 0 and solve for x

Answer 10

yes

Answer 11

was that right? (2, 0), (3, 0), (-5, 0)?

Answer 12

yes

Answer 13

thanks for helping :D

Answer 14

review
the intercept when y = 0
what value of x makes y = 0

Answer 15

you are welcome
