Q. What is (f∗g)(x)(f * g)(x)?\newlinef(x)=−5xf(x) = -5x\newlineg(x)=2x2+4xg(x) = 2x^2 + 4x\newlineWrite your answer as a polynomial or a rational function in simplest form.\newline______
  1. Identify formula: Identify the formula for (f∗g)(x)(f * g)(x).(f∗g)(x)(f * g)(x) is the product of f(x)f(x) and g(x)g(x).(f∗g)(x)=f(x)∗g(x)(f * g)(x) = f(x) * g(x)
  2. Multiply functions: We have:\newlinef(x)=−5xf(x) = -5x\newlineg(x)=2x2+4xg(x) = 2x^2 + 4x\newlineNow, we need to multiply these two functions to find (f∗g)(x)(f * g)(x).\newline(f∗g)(x)=(−5x)∗(2x2+4x)(f * g)(x) = (-5x) * (2x^2 + 4x)
  3. Distribute −5x-5x: Distribute −5x-5x across the terms in g(x)g(x):
    (f⋅g)(x)=(−5x⋅2x2)+(−5x⋅4x)(f \cdot g)(x) = (-5x \cdot 2x^2) + (-5x \cdot 4x)
  4. Perform multiplication: Perform the multiplication: f * g)(x) = \(-10x^33 - 2020x^22\
