Answer

\( f(x) = 4^{2x} \) produces the same graph as the original function.

Solution

To determine which function produces the same graph as \( f(x) = \left(8^{\frac{2}{3} x}\right)\left(16^{\frac{1}{2} x}\right) \), let's simplify \( f(x) \): 1. **Express in terms of base 2:** - \( 8 = 2^3 \) - \( 16 = 2^4 \) 2. **Rewrite \( f(x) \) using base 2:** \[ f(x) = \left(2^3\right)^{\frac{2}{3} x} \left(2^4\right)^{\frac{1}{2} x} \] 3. **Simplify the exponents:** \[ f(x) = 2^{3 \cdot \frac{2}{3} x} \cdot 2^{4 \cdot \frac{1}{2} x} = 2^{2x} \cdot 2^{2x} = 2^{4x} \] Now, let's compare this with the given options by expressing them in terms of base 2: - \( f(x) = 4^x = (2^2)^x = 2^{2x} \) - \( f(x) = 4^{2x} = (2^2)^{2x} = 2^{4x} \) - \( f(x) = 8^{3x} = (2^3)^{3x} = 2^{9x} \) - \( f(x) = 16^{2x} = (2^4)^{2x} = 2^{8x} \) Comparing the exponents, \( 2^{4x} \) matches with \( f(x) = 4^{2x} \). **Answer:** \( f(x) = 4^{2 x} \)

Beyond the Answer

To determine which function produces the same graph as \( f(x) = \left(8^{\frac{2}{3} x}\right)\left(16^{\frac{1}{2} x}\right) \), we first simplify \( f(x) \). 1. Rewrite the bases in terms of powers of 2: - \( 8 = 2^3 \) and \( 16 = 2^4 \) - Therefore, \( 8^{\frac{2}{3} x} = (2^3)^{\frac{2}{3} x} = 2^{2x} \) - And, \( 16^{\frac{1}{2} x} = (2^4)^{\frac{1}{2} x} = 2^{2x} \) 2. Now combine them: \[ f(x) = \left(2^{2x}\right)\left(2^{2x}\right) = 2^{2x + 2x} = 2^{4x} \] 3. Next, express \( 2^{4x} \) in terms of the given options: \[ 2^{4x} = (2^2)^{2x} = 4^{2x} \] This means that \( f(x) = 4^{2x} \) produces the same graph as the original function. Thus, the answer is: \( f(x) = 4^{2x} \)
