If \( f(x) \) is an exponential function where \( f(-3) = 27 \) and \( f(0.5) = 83 \), then find the value of \( f(0) \), to the nearest hundredth.

Answer :

Final answer:

To find the value of f(0) for an exponential function, we can use the given values of f(-3) and f(0.5) to determine the equations for a and b. Solving these equations will allow us to calculate the value of f(0).


Explanation:

To find the value of f(0), we need to use the given information. We know that f(-3) = 27 and f(0.5) = 83. Since f(x) is an exponential function, we can write it in the form f(x) = a*b^x, where a is the initial value and b is the base. From f(-3) = 27, we can substitute x = -3 and f(x) = 27 into the exponential function equation:

27 = a*b^(-3)

Similarly, from f(0.5) = 83, we can substitute x = 0.5 and f(x) = 83 into the equation:

83 = a*b^(0.5)

Solving these two equations simultaneously will give us the values of a and b. Substituting a and b back into the exponential function equation, f(0) can be calculated.
