What was the graph of the equation x equals negative 4 look like

It will be a vertical line parallel to y-axis, passing through point , the graph is shown below.

Step-by-step explanation:

Mark the point , it will lie on x-axis.

Drop a perpendicular line passing through parallel to y-axis.

That is the require graph.

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.
