Hope this helps and I hope u have an Amazing day!!
Answer: x=2
Step-by-step explanation:
Slope = (-2 + 7)/(9 - 3) = 5/6
y = mx + b
-7 = 5/6(3) + b
b = -7 - 5/2
b = - 19/2
equation
y = 5/6x - 19/2
standard form
5/6x - y = 19/2 or 5x - 6y = 57
Answer:
D
Step-by-step explanation:
Looks like a transformation of x^2 where it is stretched vertically.
When x = 1 , f(x) = 4 and when x = 2 f(x) = 16
Yes its f(x) = 4x^2
