calculus
posted by Heatherneeding help!!!! .
I have two questions, please help.
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^26x+5
Then find the
a. vertex
b. axis of symmetry
c. intercepts, if any

f(x) = 2(x^22x) + 7
= 2(x^22x+1) + 7 + 2
= 2(x1)^2 + 9
f(x) = x^26x+5
= x^26x+9 + 59
= (x3)^2  4
now you know all there is to know about the parabola.
