1 + -3 1/2 is = to -2.5 so v= -2.5
Answer:
47
Step-by-step explanation:
a line adds up to 180 so 180-133=47
The vertical asymptote requires a factor of (x-4) in the denominator.
The double zero requires a factor of (x-1)² in the numerator.
At x=0, these factors will give a value of (-1)²/(-4) = -1/4, so another constant factor of -12 is needed to make the y-intercept be 3.
Your rational function is ...
... y = -12(x -1)²/(x -4)
The gradient is 2.
You divide the increase in y (2) by the increase in x (1)
It would be the first one and the third one then the last
