Question

d)

\\( f(x) = -2^{x-2} \\)

\\( f(x) = 2^{2-x} \\)

\\( f(x) = 4 - 2^x \\)

\\( f(x) = 2^x - 4 \\)

Explanation:

Identify key points and asymptote from the graph

$$ LATEXBLOCK0 $$

Test the given options at \(x = 0\)

$$ LATEXBLOCK1 $$

Verify the correct option at \(x = 2\)

$$ f(2) = 2^{2-2} = 2^0 = 1 $$

Answer:

  • (A) \(f(x) = -2^{x-2}\)
  • (B) \(f(x) = 2^{2-x}\) (Correct answer)
  • (C) \(f(x) = 4 - 2^x\)
  • (D) \(f(x) = 2^x - 4\)
