Select the correct answer.
Use a graphing tool to solve the equation for x.
-3x+2+4^x+2

A.
x ≈ -0.15
B.
x ≈ -0.24
C.
x ≈ -0.36
D.
x ≈ 2.72

Answer 1

x ≈ -0.24

Step-by-step explanation:

Using a graphing tool to graph the given equation, we will end up with the graph shown in the attached image.

Now, to solve the equation means to find the x-intercept.

Taking a look at the graph, we would find that the x-intercept is somewhere between the -0.2 and the -0.3

This means that the best choice is x ≈ -0.24

We can check using algebraic substitution:

-3x + 2 = -3(-0.24) + 2 = 2.72

4ˣ +2 = 4⁻⁰.²⁴ + 2 = 2.7169

We can note that the two values are almost equal.

Hope this helps :)
