-10,-17, -24, -31, -38, ... a) Common Difference:
b) Recursive Formula:
c) Explicit Formula:
d) 843

i think the correct option is the second option.

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.

the answer is  

d.

21

i did this one. so you should get it right.
