Evaluate Exponential Functions • Substitute given values for x in the given functions. • Simplify Given f(x) = 3(2)x, find: f(1)=f(3)= f(0) =
Substitute given values for x in the given functions. • Simplify Given f(x) = 3(2)x, find: f(5)= f(2)= f(1)=
Solve Exponential Equations • Isolate the exponential expression with an exponent of “x” on one side of the equation. • Rewrite the expression on the other side of the equation as a power of the same base as the one with the exponent of “x”. • Set the exponents equal to each other and solve for x. 2x = 8 23x = 162 7x= 343
Isolate the exponential expression with an exponent of “x” on one side of the equation. • Rewrite the expression on the other side of the equation as a power of the same base as the one with the exponent of “x”. • Set the exponents equal to each other and solve for x. (8)x = 64 ( ) x = 4x = 16
