Question

Find the axis of symmetry:
f(x) = 3(x + 4)^2 + 1
g(x) = 2x^2 –16x + 15

Answer 1

what is x

Answer 2

h(x)=a(x-1)-3

Answer 3

Explain how to find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest).

those are the instructions

Answer 4

where did you get h(x from?

Answer 6

Find the axis of symmetry:
f(x) = 3(x + 4)^2 + 1
g(x) = 2x^2 –16x + 15 Note that these are two separate parabolas, two separate questions.

In f(x)=a(x-h)^2 + k, the vertex is given by (h, k).

Can you use this info to find the x-coordinate of the vertex of each given parabola?

Answer 7

f (x), the expression is in vertex form: a(x-h)^2 +k. The variables h and k represent the vertex so (-4, 1) The axis of symmetry is -4.

Answer 9

Nice work! How about finding the ax. of sym. for the 2nd function?

Answer 10

Convert it to vertex form but howww?
