Use the graph to estimate the solutions to 4 log2 (2x) = x + 4. Select all that apply.
Elanso [62]

Given:

The equation is:

4\log_2(2x)=x+4

The graph of the 4\log_2(2x) and x+4 are given on a coordinate plane.

To find:

The solution of the given equation from the given graph.

Solution:

From the given graph it is clear that the graphs of 4\log_2(2x) and x+4 intersect each other at points (1.24,5.24) and (16,20).

It means the values of both functions 4\log_2(2x) and x+4 are equal at x=1.24 and x=16.

So, the solutions of given equation are x=1.24 and x=16.

Therefore, the correct option is only F.

I really need help with this thanks a lot
aleksandrvk [35]

Answer:

  • Graph B

Step-by-step explanation:

<u>According to data in the table we see pairs of points:</u>

  • (3, 75), (5, 125)

<u>This gives us the rate of change:</u>

  • (125 - 75)/(5 - 3) = 50/2 = 25

<u>The y - intercept is zero:</u>

  • 75 = 3*25 + b
  • 75 = 75 + b
  • b = 0

<u>The line is:</u>

  • y = 3x

This is the line on the graph B

<u>Note.</u> <em>Its not clear what is needed regarding the table on the bottom</em>
