Each graph will simply be one unit higher than the previous one, or one unit greater in the vertical respect. At any point they will have the same velocity and acceleration, ie the curve will be identical in every other respect other than the relative height of the curve with respect to the x-axis.

Use the substitution method
f(x)= 3-2x
f(4)= 3-2(4)
Do multiply first then subtract
= 3-8
= -5
Answer : f(4)= -5
The value of 64/225 is in the lowest state, but in decimal form, the value equals 0.284444
If you follow PEMDAS, multiplication would be first, so 3*2 is 6, then it's addition.
So 3*2=6 and 8*-16 is -128, then you add them both.
So 6+(-128) is equals to -122. YOU'RE WELCOME :D
