[tex]\[
\begin{tabular}{|l|l|}

\][/tex]

A. [tex]f(x)[/tex] has a greater slope.
B. [tex]g(x)[/tex] has a greater slope.
C. The slopes of [tex]f(x)[/tex] and [tex]g(x)[/tex] are the same.
D. The slope of [tex]g(x)[/tex] is undefined.



Answer :

Let's determine which function has a greater slope by comparing the slopes of [tex]\( f(x) \)[/tex] and [tex]\( g(x) \)[/tex] step-by-step.

### Step 1: Determine the slope of [tex]\( f(x) \)[/tex]

The function [tex]\( f(x) = 4x + 10 \)[/tex] is a linear function of the form [tex]\( y = mx + b \)[/tex], where [tex]\( m \)[/tex] is the slope. Here, [tex]\( m = 4 \)[/tex]. Therefore, the slope of [tex]\( f(x) \)[/tex] is 4.

### Step 2: Determine the slope of [tex]\( g(x) \)[/tex]

To determine the slope of [tex]\( g(x) \)[/tex], we can use the given points from the table:

[tex]\[ \begin{array}{|c|c|} \hline x & g(x) \\ \hline 2 & 5 \\ \hline 4 & 7 \\ \hline 6 & 9 \\ \hline \end{array} \][/tex]

The slope of a function between two points [tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex] is given by:

[tex]\[ \text{slope} = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]

Let's use the first two points [tex]\((2, 5)\)[/tex] and [tex]\((4, 7)\)[/tex] to find the slope of [tex]\( g(x) \)[/tex]:

[tex]\[ \text{slope of } g(x) = \frac{7 - 5}{4 - 2} = \frac{2}{2} = 1 \][/tex]

### Step 3: Compare the slopes

We now have:

- The slope of [tex]\( f(x) \)[/tex] is 4.
- The slope of [tex]\( g(x) \)[/tex] is 1.

Since [tex]\( 4 > 1 \)[/tex], the slope of [tex]\( f(x) \)[/tex] is greater than the slope of [tex]\( g(x) \)[/tex].

### Conclusion

Based on the comparison, the function [tex]\( f(x) \)[/tex] has a greater slope.

Thus, the correct statement is:

[tex]\( f(x) \)[/tex] has a greater slope.
