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)= x 2 −3x:f \left(x\right) = x^{2} - 3 x :

  1. ⓐ Evaluate f(5).f \left(5\right) .
  2. ⓑ Solve f(x)=4.f \left(x\right) = 4.
