Answer: x = -0.75
-0.72 -0.65
Step-by-step explanation:
Consider the equation below.
3^(-x) - 3 = 4^x - 1
consider the values of x = 1.75, -1.5, -1.25, -1, -0.75,-0.5,-0.25
x 3^(-x) -3 4^x - 1
-1.75 3.83 -0.91
-1.5 2.19 -0.88
-1.25 0.95 -0.82
-1 0 -0.75
-0.75 -0.72 -0.65
-0.5 -1.27 -0.50
-0.25 -1.68 -0.29
The bold values when x = -0.75 gives -0.72 and -0.65 is the approximate solution to the equation
by approximation -0.72 when rounded off = -0.7
and -0.65 when rounded off = -0.7
