If using the radius, you would multiply the radius by 2*pi, to calculate the circumference, which should be the same as the answer i got.
In the attached, the dotted red graph is g(x). The solid black graph is the function shifted 5 units left.
F(-1)
replace all x with -1
f(-1)=-3(-1)^2+2(-1)-7
f(-1)=-3(1)-2-7
f(-1)=-3-9
f(-1)=-12
