Given the following function, find the coordinates of the vertex of f(x): f(x) = x2 - 2x – 15
A. (1, -16)
B. (-1, -12)
C. (-1, -14)
D. (1, -17)

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

i think it would be c
