Solution
Solution Steps
To find x such that f(x)=528.38 for the function f(x)=(4.5)x, we need to solve the equation (4.5)x=528.38. This can be done by taking the logarithm of both sides and then solving for x.
Step 1: Set Up the Equation
We start with the function defined as f(x)=(4.5)x and set it equal to the given value:
(4.5)x=528.38
Step 2: Apply Logarithms
To solve for x, we take the logarithm of both sides:
log((4.5)x)=log(528.38)
Using the property of logarithms, we can simplify the left side:
