Question

What is the equation of the line of symmetry for the graph of y = -2(x - 4)2 + 3?

x = -2
x = 2
x = 3
x = 4

Answer 1

is your equation y = -2(x - 4)2 + 3 or y = -2(x - 4)^2 + 3

Answer 2

^2

Answer 3

ok well first start by distributing

Answer 4

CouldI put the x answers into the equation?

Answer 5

not yet

Answer 6

so what do you get after you distribute?

Answer 7

y = -2x^2+8^2+3 correct?

Answer 8

Answer 9

you already have this in vertex form, your axis of symmetry is the first coordinate of your vertex
