Math Problem Statement

Use the graph of the function g to determine the answers to the following: a. Vertical Intercept b. Horizontal Intercepts c. Evaluate g(3) d. Solve g(x) = -3

Solution

Let's break down the problem based on the graph you provided.

We are asked to use the graph of the function gg to answer several questions:

a. Vertical Intercept

The vertical intercept (or y-intercept) is where the graph crosses the y-axis, i.e., when x=0x = 0.

From the graph:

  • At x=0x = 0, the function intersects the y-axis at approximately y=3y = 3.

So, the vertical intercept is (0,3)(0, 3).

b. Horizontal Intercepts

The horizontal intercepts (or x-intercepts) occur where the graph crosses the x-axis, i.e., where g(x)=0g(x) = 0.

From the graph:

  • The function crosses the x-axis at two points: approximately x=2x = -2 and x=4x = 4.

Thus, the horizontal intercepts are (2,0)(-2, 0) and (4,0)(4, 0).

c. Evaluate g(3)g(3)

To evaluate g(3)g(3), we look at the point on the graph where x=3x = 3.

From the graph:

  • When x=3x = 3, g(3)2g(3) \approx 2.

So, g(3)=2g(3) = 2.

d. Solve g(x)=3g(x) = -3

To solve g(x)=3g(x) = -3, we need to find the x-value(s) where the function equals -3.

From the graph:

  • The function reaches g(x)=3g(x) = -3 at approximately x=1x = -1.

So, the solution to g(x)=3g(x) = -3 is x=1x = -1.


Would you like more detailed explanations, or do you have any other questions?

Here are five related questions:

  1. How would you determine the domain and range of the function based on the graph?
  2. What is the maximum value of the function gg, and at what point does it occur?
  3. Can you describe the intervals where the function is increasing and decreasing?
  4. How would you solve for g(x)=1g(x) = 1 using the graph?
  5. What is the symmetry of the graph? Is the function even, odd, or neither?

Tip: When analyzing graphs, always start by identifying key features such as intercepts, maxima/minima, and behavior at infinity to gain insights into the function's properties.
