Answer:
Which of the following is the scaling factor a of the function f(x) = 3|x|?
Step-by-step explanation:
Answer:
y = 5/2x
y = 35/2
Step-by-step explanation:
direct variation
y = kx
Substitute the values for x and y
15 = k(6)
Divide each side by 6 yo find k
15/6 = k
5/2 = k
The equation is y = 5/2 x
Now we know x =7
y = 5/2(7)
y = 35/2
the answer is B or D. I mean both doesnt really matter which one. We can see that graph fallows cubic function pattern when x < 2 and option A is saying oposite (when x > 2). Option C cannot be the answer because there is graph when x is larger than 2 and that option doesnt define function when x is larger than 2.
So, B and D
