PLEASE HELP WITH THIS GEOMETRY QUESTION photo attached above!!!

12: an enclosed shape that has no curves

13: I is a quadrilateral, bc it has four sides

Step-by-step explanation:

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.

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
