explanation

if we use a graphing calculator, there is only one such number $c\in[0.5,0.75]$ that satisfies the conclusion of the mean value theorem, that is, a number $c\in[0.5,0.75]$ such that

$f'(c) = \dfrac{f(0.75) - f(0.5)}{0.75-0.5},$

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.

a.N+3>4

Step-by-step explanation:

Let N be the number

According to question

Sum of N and 3 is given by

N+3

Atleast means greater than or equal to

At-least 4 means greater than or equal to 4

Therefore,

$N+3\geq 4$

Hence, the inequality for the given sentence is given by

$N+3\geq 4$

a.N+3>4
