Benny bought a coke for two dollars and six candy bars. He spent a total of twelve dollars. How much did each candy bar cost.
USE X VOR VARIABLE ex.( x = answer)

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

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.
