1. Uss completing the square to describe the graph of the following function. Support your answers graphically.

f(x)= -2x^2+4x+7

please show work.

2. Can someone help me to graph this function?

f(x)=x^2-6x+5

Then find the

a. vertex

b. axis of symmetry

c. intercepts, if any

- calculus -

= -2(x^2-2x+1) + 7 + 2

= -2(x-1)^2 + 9

f(x) = x^2-6x+5

= x^2-6x+9 + 5-9

= (x-3)^2 - 4

now you know all there is to know about the parabola.
