Define the following functions:
• f(x) = $$x^2$$
• g(x) = $$2*x + 1$$
• h(x) = $$\sqrt{x + 4}$$
• k(x) = $$\ln(x + 5)$$
Evaluate the composite function values at x = 3 as follows:
• f(g(3)): g(3) = 2*3 + 1 = 7, so f(g(3)) = 49
• f(h(3)): h(3) = $$\sqrt{7}$$ so f(h(3)) = 7
• f(k(3)): k(3) = $$\ln(8)$$ $$\approx 2.08$$, so f(k(3)) $$\approx (2.08)^2 \approx 4.32$$
• f(3) = 9
Rank these values from smallest to largest.
