Solution
Let's analyze the given graph of the parabola to determine the required values:
a. Domain of the function
The domain of a function is the set of all possible x-values that the function can take. For this parabola, which extends infinitely in both the positive and negative directions along the x-axis:
Domain:
b. Range of the function
The range of a function is the set of all possible y-values that the function can take. Since this is a parabola that opens upwards with the vertex at , the lowest y-value is and it extends infinitely upwards.
Range:
c. x-intercepts
The x-intercepts are the points where the function intersects the x-axis. From the graph, we can see that the parabola intersects the x-axis at and .
x-intercepts:
d. y-intercept
The y-intercept is the point where the function intersects the y-axis. From the graph, we can see that the parabola intersects the y-axis at .
y-intercept:
e. Missing function values
To find and , we can read the corresponding y-values from the graph for these x-values.
So, the required values are:
f(-2) = 5
f(2) = -3
