I have been working on these 2 problems and I think I am confusing myself. I have never tried this site before but it was recommended to me. I appreciate whoever can help me. Thanks in advance

The first question is

f(x)=-2x^2 + 2x + 8

I need to find the x and y coordinates of the vertex the line of symmetry and the max/min of f(x)

also the value of f(1/2) =17/2

The 2nd question has a fraction and I think this is confusing me on this one

f(x)=1/5(x+7)^2+7

I need to find the vertex line of symmetry max/min and is the value f(-7)=7 a minimum or a maximum?
