To identify the hidden behaviour of the function
The behaviour of the function around
Given the function:
Graph the function
window and analyse the graph for the hidden behaviour:
The function
It seems like the function has a critical point at
Now, the function has a zero around
But, it is not clear.
Thus, the behaviour of the function
Graph the function
The dimensions of the viewing window is set to be
It is clear that the function has a zero at
Hence, the hidden behaviour is understood.
Conclusion:
The behaviour of the function around

- Consider the function f(x) = x²-1. (a) Find the instantaneous rate of change of f(x) at x=1 using the definition of the derivative. Show all your steps clearly. (b) Sketch the graph of f(x) around x = 1. Draw the secant line passing through the points on the graph where x 1 and x-> 1+h (for a small positive value of h, illustrate conceptually). Then, draw the tangent line to the graph at x=1. Explain how the slope of the tangent line relates to the value you found in part (a). (c) In a few sentences, explain what the instantaneous rate of change of f(x) at x = 1 represents in the context of the graph of f(x). How does the rate of change of this function vary at different points?arrow_forward1. The graph of ƒ is given. Use the graph to evaluate each of the following values. If a value does not exist, state that fact. и (a) f'(-5) (b) f'(-3) (c) f'(0) (d) f'(5) 2. Find an equation of the tangent line to the graph of y = g(x) at x = 5 if g(5) = −3 and g'(5) = 4. - 3. If an equation of the tangent line to the graph of y = f(x) at the point where x 2 is y = 4x — 5, find ƒ(2) and f'(2).arrow_forwardDoes the series converge or divergearrow_forward
