41. find all solutions to the following equations. remember to check for extraneous solutions.
1. log2(3x + 7) = 4

Ans.

X=3

Step-by-step explanation:

Ok, there are several ways to solve this, I chose the one that can be more visual friendly to you.

SInce the log are based 2, we are going to be using this base on both sides of the equation, so, let Y = (3X+7).

This means.

Since Y = (3X+7)

Therefore X=3

Best of luck.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !
