Q. 55 - Algebra 2

Question

For exercises $\mathbf{53}-\mathbf{55},$ use the following information.

Suppose the temperature $T^o\left(C\right)$ below Earth’s surface is given by $T\left(d\right)=35d+20$, where $\mathbf{d}$ is the depth $\left(\mathbf{km}\right).$

Graph of the linear function.

Step-by-Step Solution

Answer

The graph of the given function is:

Step 1. Given information

A linear function $T\left(d\right)=35d+20$.

Step 2. To find the coordinates of the function

From the given information,

$T\left(d\right)=35d+20$

When $d=0\Rightarrow T\left(0\right)=20$, coordinate is $(0,20)$

When $d=1\Rightarrow T\left(1\right)=55$, coordinate is $(1,55)$

When $d=2\Rightarrow T\left(2\right)=90$, coordinate is $(2,70)$

Step 3. Graph of the function

The graph of the given function is:
