Step-by-step explanation:
Answer:
x ≈ -0.24
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 :)
