Answer:
4
Step-by-step explanation:
We have been given that it equals 19 when added to 3 and multiplied by 4 so follow these steps:
1. set the equation 4x+3=19
2. solve for x
4x+3-3=19-3
This is used to solve for x
3. 4x=16 is found
4. if 4x=16, we divide 16/4 and get 4!
That's your answer hope it helped!
F(2)= 4(16) - 6(4) + 8(2) - 15
F(2)= 64 -24 + 16 - 15
F(2)= 41
