Question

Can someone plss help me with this!!

Answer 1

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.

Answer 2

f(3) = -11, f(-7) = 19

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
