Which equations show the identity property of multiplication?
choose exactly two answers that are correct.
a.
4.2 = 1 • 4.2
b.
0 • (–8) = 0
c.
–3 • 1 = –3
d.
-1/4 • (–4) = 1

1) is right

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.
