4. Graph the relation shown in the table. Is the relation a function? Why or why not?

(-5, -5)
(-3, -3)
(1, 1)
(2, 2)

Yes; no vertical line passes through two graphed points.

No; a vertical line passes through two graphed points.

Yes; no horizontal line passes through two graphed points.

No; a horizontal line passes through two graphed points.

Step-by-step explanation:

The first one.

Yes, vertical line test

A. Yes; no vertical line passes through two graphed points

Step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
