Avg difficulty 2.5

Evaluate f(−3),f(2),f(−a),−f(a),f(a+h). f \left(−3\right) , f \left(2\right) , f \left(− a\right) , − f \left(a\right) , f \left(a + h\right) .

Given the function f(x)=8−3x:f \left(x\right) = 8 - 3 x :

  1. ⓐ Evaluate f(−2).f \left(- 2\right) .
  2. ⓑ Solve f(x)=−1.f \left(x\right) = - 1.
