Answer:
f(x) = 6x-16
Step-by-step explanation:
Since the function is shifting 4 units down, it will be moving down the y axis, meaning the y-intercept will decrease by 4.
y=mx+b is the formula for the straight line, where b is the y-intercept. The y-intercept in this function is -12, so we would just subtract -4 from -12 to get our answer.
-12-4=-16
Make sure to leave the coefficient of x
Therefore, f(x) = 6x-16
115*20=2300.
50*5=250
