In the above case, the vertex of g(x) = 8x2 - 48x + 65 is (3.-7).
What is the vertex about?
A vertex in regards to maths is known to be the top of the head of a graph and it is said to be any given point of an angle, graph, etc. that helps to end a line or curve.
Since the vertex of g(x) = 8x2 - 48x + 65
You then find and write the properties of he function and this will be:
vertex of g(x) = 8( x-3)^2 -7
So the vertex of g(x) = 3, -7.
Note that when the equation of 8x2 - 48x + 65 is graphed, the vertex will be found at point (3,-7) on a graph and as such option b is correct.
