Question

How many x-intercepts does the graph of y = x2 have?

Answer 1

I have no clue how to solve this... and the sad thing is.... it's probably really easy...

Answer 2

what is the value of y when we want to find a point on the x axis?

Answer 3

@amistre64 0

Answer 4

then, when y=0, we find the values for x

y=x^2

0=x^2 when?

Answer 5

we find the sqrt of 0 and x^2?

Answer 6

we could, but this is simple enough:


x^2 means: x*x

x*x = 0 when x=?

Answer 7

0?

Answer 8

I hate zeros... too many rules

Answer 9

yes, and since there is only one value of x that makes this statement true; then y=x^2 has only 1 x intercept

Answer 10

okay I think I get it now

Answer 11

there are harder ones, but the concept is the same :)

Answer 12

okay thanks!
