Answer:
f(3) = -11, f(-7) = 19
Step-by-step explanation:
f(x) = -3x -2
1.
f(3) is the f(x) when x = 3 so where we see x in the equation we write 3 and calculate
f(3) = -3(3) -2 = -9 -2 = -11
2.
f(-7) = f( x= -7) = -3(-7) -2 = 21 -2 = 19
Answer: 1) f(3)= -11 and 2) f(-7)= 19
Step-by-step explanation: f(x) means 'function of x' or just to replace x with the desired value. For example, f(3) just means x=3. Following below is written proof.
