Given the function f(x) = -4x + 2, what is the
value of f(3)?

What is the answers

f(3)=-10

Step-by-step explanation:

f(3)=-4(3)+2=-12+2=-10

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.
