The function f(x) = −2x + 5 is changed to f(x) = 2x + 5. which describes the effect of the change on the graph of the original function? a) the line will be steeper. b) the line will be less steep. c) line changes from increasing to decreasing. d) line changes from decreasing to increasing.

As the Slopes of both the Functions are Same, They are Equally Steep.

⇒ Option A and Option B cannot be the Answers

As the First Line Slope is Negative and As the Second Line Slope is Positive, The Line Changes from Decreasing to Increasing

⇒ Option D is the Answer

their is no graph showing

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.
