Question

7. Try It #7 Look at the graph in Figure 22 and identify the following for the function j(t):

e. Is j(t) an increasing or decreasing function (or neither)?

Answer 1

The function of j(t) is decreasing.

Explanation:

In the question two functions are given as h(t)=3t-4 and j(t)=5-t.

It is required to find whether j(t) is an increasing/decreasing or neither function.

To solve this question, first find the slope of the function. If, the slope is positive the function is increasing and if the slope is negative the function is decreasing.

Step 1 of 1

Find the slope of the function j(t) by comparing these to the standard form.

y=mx+b

Then, m=-1

Since the slope is negative.

Therefore, the function is decreasing.
