rubbing it against your hair it causes friction and with friction comes energy
No answers at all! (C) 2x-5y cannot equal two things at once.
I think your equation is wrong. the domain of f(x)= 5x+2 is ALL REAL NUMBERS. That means it’s negative infinity to positive infinity.
Answer:
(-1, 2) — derivative is zero
Step-by-step explanation:
A critical point of a function is a point at which the slope is <em>zero</em> or <em>undefined</em>. (The critical point must actually be in the domain of the function. Vertical asymptotes are <em>not</em> critical points.)
You find the answer by looking for points on the graph where a tangent to the function is horizontal or vertical.
__
In the given graph, the curve approaches horizontal near the point (-1, 2), so it is reasonable to estimate that that point is a critical point.
The attached graph also shows the inverse function. That has a critical point at (2, -1), where the slope is undefined (a tangent to the graph is vertical).
__
The graph of a circle or ellipse does not pass the vertical line test, so is not a function. However, the graph still has critical points where the tangents are vertical or horizontal. The second attachment shows those critical points.
