Question

What are the vertex, the axis of symmetry, the maximum or minimum value, the domain and the range of each function? f (x) = 2(x-4)2 + 3

Answer 1

To find the vertex use -b/2a
The equation distributed would be 2x^2-16x+35
a: 2 b:-16 c:35

Now find the x for the vertex. -b/2a which is 16/2(2) and that is 4

Now fill 4 into the original equations and you get and you get 3. So, the vertex is (4,3)
Axis of symmetry is x=4

Answer 2

Minimum is (4,3)

Answer 3

Domain and Ranger are all real numbers

Answer 4

what about the axis of symmetry

Answer 5

I put it in the first answer. it's x=4

Answer 6

ok thank you
