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: (,)(-\infty, \infty)

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 (1,4)(1, -4), the lowest y-value is 4-4 and it extends infinitely upwards.

Range: [4,)[-4, \infty)

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 (1,0)(-1, 0) and (3,0)(3, 0).

x-intercepts: 1,3-1, 3

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 (0,3)(0, -3).

y-intercept: 3-3

e. Missing function values

To find f(2)f(-2) and f(2)f(2), we can read the corresponding y-values from the graph for these x-values.

  • f(2)=5f(-2) = 5
  • f(2)=3f(2) = -3

So, the required values are:

f(-2) = 5
f(2) = -3

Summary

a. Domain: (,)(-\infty, \infty)

b. Range: [4,)[-4, \infty)

c. x-intercepts: 1,3-1, 3

d. y-intercept: 3-3

e. f(2)=5f(-2) = 5 and f(2)=3f(2) = -3
