The solution to the equation 2-5^x = 2^x - 3 is x = 0.75
How to solve the question?
Substitute the given values of x in the given expression,
Option A:
LHS = f(-1.25) = -1.866
RHS = f(-1.25) = -2.58
Option B:
LHS = f(1.25) = -5.48
RHS = f(1.25) = -0.62
Option C:
LHS = f(0.75) = -1.34
RHS = f(0.75) = -1.32
Option D:
LHS = f(-0.75) = 1.70
RHS = f(-0.75) = -2.40
when x = 0.75, LHS close to RHS.
Hence, the solution to the equation 2-5^x = 2^x - 3 is x = 0.75
