I’ve been on this question for a while and I’m having a lot of trouble answering it

Axis: x=2, vertex: (2,4)

Step-by-step explanation:

To find the axis of symmetry and vertex you need the formula -b/2a.

In this case, b is 4 and a is -1. Therefore, the value is -4/-2 or 2.

So the, axis is x=2 and so is the x-value of the vertex. Now to find the y value of the vertex, plug in the x-value(2) into the equation.

>-(2)^2 +8

>-4+8

>4

5x+10 is the correct one
