Q. Use the following function rule to find f(−9)f(-9).\newlinef(x)=−5−11xf(x) = -5 - 11x\newlinef(−9)=f(-9) = _____
  1. Plug in xx for f(x)f(x): Plug in –9–9 for xx in the function f(x)f(x).\newlinef(–9)=–5–11(–9)f(–9) = –5 – 11(–9)
  2. Multiply 1111 by −9-9: Multiply 1111 by –9–9.f(–9)=–5+99f(–9) = –5 + 99
  3. Add −5-5 to 9999: Add –5–5 to 9999.f(–9)=94f(–9) = 94
