Explanation:

Analyze the base function features

Assume the base function is an exponential growth function \(f(x) = 2^x\), which has a \(y\)-intercept at \((0,1)\), an asymptote at \(y=0\), and increases as \(x\) increases.

Match each transformation

  • For \(j(x) = f(x+2)\):
$$ j(0) = f(2) = 2^2 = 4 \implies y\text{-intercept at } (0,4) $$
  • For \(h(x) = f(x) + 2\):
$$ \text{Vertical shift up by 2} \implies \text{asymptote at } y = 2 $$
  • For \(g(x) = 2f(x)\):
$$ g(0) = 2f(0) = 2(1) = 2 \implies y\text{-intercept at } (0,2) $$
  • For \(m(x) = -f(x)\):
$$ \text{Reflection across the } x\text{-axis} \implies \text{function decreases as } x \text{ increases} $$

Answer:

TransformationFeature
\(h(x) = f(x) + 2\)asymptote of \(y = 2\)
\(g(x) = 2f(x)\)\(y\)-intercept at \((0,2)\)
\(m(x) = -f(x)\)function decreases as \(x\) increases
