Concept explainers
To check whether the graph of the given function has an x -intercept sometimes, always or never.
Answer to Problem 42HP
Never
Explanation of Solution
Given:
Equation:
Calculation:
A graph of the equation can be used to find out whether the equation has x -intercepts or not.
Let a = 3.5 and b = 2.
Graph:
Plotting the aboveequation on a graphing utility,
Inference:
From the above graph, it is seen that the graph will never have an x- intercept since, the graph will approach x -axis, but never crosses it.
Also, the function is an exponential function. Therefore, it will have an asymptote.
