The Effect of the Coefficient on the Graph

Oct 13, 2025 by orovajewels.com 133 views

The parent function $f(x) = |x|$ is a well-known absolute value function. Its graph is a V-shaped graph with its vertex at the origin (0, 0). The graph is symmetric about the y-axis, and it has a slope of 1 on the right side and a slope of -1 on the left side.

The Effect of the Coefficient on the Graph

When we introduce a coefficient 'a' into the function, it affects the graph's width and height. In this case, we want to find the value of 'a' that makes the graph of $f(x) = a|x|$ wider than that of the parent function $f(x) = |x|$ .

The Relationship Between the Coefficient and the Graph's Width

To understand how the coefficient affects the graph's width, let's consider the graph of $f(x) = |x|$ . The graph has a slope of 1 on the right side and a slope of -1 on the left side. When we multiply the function by a coefficient 'a', the slope of the graph changes. If 'a' is greater than 1, the slope of the graph increases, and the graph becomes steeper. If 'a' is less than 1, the slope of the graph decreases, and the graph becomes less steep.

Determining the Value of 'a'

To make the graph of $f(x) = a|x|$ wider than that of the parent function $f(x) = |x|$ , we need to find the value of 'a' that makes the graph less steep. This means that we need to find the value of 'a' that is less than 1.

Analyzing the Options

Let's analyze the options given:

A. $-1$ : This value of 'a' would make the graph of $f(x) = a|x|$ steeper, not wider.
B. $\frac{1}{4}$ : This value of 'a$ is less than 1, which means that the graph of $f(x) = a|x|$ would be less steep and wider than that of the parent function $f(x) = |x|$ .
C. $1$ : This value of 'a$ would make the graph of $f(x) = a|x|$ the same as that of the parent function $f(x) = |x|$ .
D. $4$ : This value of 'a$ would make the graph of $f(x) = a|x|$ steeper, not wider.

Conclusion

Based on our analysis, the value of 'a' that makes the graph of $f(x) = a|x|$ wider than that of the parent function $f(x) = |x|$ is $\frac{1}{4}$ .
