Question

Solve the equation for x by graphing. 2^x - 4 = -4^x + 4

Answer 1

X~1.25. All you have to do is graph the function and see where the graph crosses the x-axis.

Answer 2

Draw 2 graphs on same grid. Where they intersect is the solution

y = 2^x + 4
y = -4^x - 4

Approximate answer is x = 1.25
