Question

use the graph to the right to complete the following. for the graph, tick marks along the axes represent one unit each.

a. determine the x-intercepts, if any.
b. determine the y-intercepts, if any.

a. what is/are the x-intercept(s)? select the correct choice below and, if necessary, fill in the answer box to complete your choice.

a. the x-intercept(s) is/are
(type an integer or a simplified fraction. use a comma to separate answers as needed.)
b. there is no x-intercept.

b. what is/are the y-intercept(s)? select the correct choice below and, if necessary, fill in the answer box to complete your choice.

a. the y-intercept(s) is/are
(type an integer or a simplified fraction. use a comma to separate answers as needed.)
b. there is no y-intercept.

Identify the x-intercept from the graph

Using the Graph Interpretation and Quadratic Intercepts Analysis knowledge points
\[
\text{The line crosses the } x\text{-axis at } (3, 0).
\]
\[
\text{Thus, the } x\text{-intercept is } 3.
\]

Identify the y-intercept from the graph

Using the Graph Interpretation and Quadratic Intercepts Analysis knowledge points
\[
\text{The line crosses the } y\text{-axis at } (0, 4).
\]
\[
\text{Thus, the } y\text{-intercept is } 4.
\]
