Question

The graph of the equation y = x2 – 7 is symmetric with respect to which of the following?

the line at y = –x + 7
the y–axis
the x–axis
the line at y = x

Answer 1

here's a hint.. look at the exponents of x^2 - 7 what do you see?

Answer 2

a 2? (i don't get the hint)

Answer 3

is that even or odd?

Answer 4

even?

Answer 5

therefore it is symmetric with respect to the y-axis

Answer 6

so if it's odd, it'd be symmetric to the x-axis?

Answer 7

yes

Answer 8

by the way... the exponents of x^2 - 7 are 2 and 0 <--both even

Answer 9

okay, thanks. :)

Answer 10
