Question

Consider the quadratic function y = 1.6 (x-5)2 - 6.5.

Determine the axis of symmetry, x = _____

Answer 1

Do you know about,

a(x-h)^2 + k

??

Answer 2

no

Answer 3

This is the vertex form of the equation.
Whenever you have anything as such, you can simply find the vertex,

a(x-h)^2 + k

the sign of term with "x" inside the bracket is changed to it's opposite sign and k remains the same.
The vertex is, (h,k)

Answer 4

Like let's say if you have something like,

a(x-2)^2 +3

So vertex = (2,3)

now try your problem. :)

Answer 5

thankyou soo mucch

Answer 6

Welcome.

Answer 7

so its 5,6.5?

Answer 8

It's
(x,y)

the x is correct, you forgot the negative sign with y.
rest all is perfect.

Answer 9

ok thankss :)

Answer 10

So it will be,
(5,-6.5)

Answer 11

And welcome.
