The value of the functions are f(0) = -2, f(-1) = 0, f(-2) = 2 and f(-2) = 2
The function does not cross the origin
The function has 3 x intercepts
How to evaluate the function
From the question, we have the following parameters that can be used in our computation:
The graph
Also, we have
The function values
The notation f(0) means that we calculate y when x = 0
From the graph, we have
f(0) = -2
Using the above as a guide, we have the following:
f(-1) = 0, f(-2) = 2 and f(-2) = 2
The function does not cross the origin because it does not pass through (0, 0)
Also, the function has 3 x intercepts because it crosses the x-axis three times
