Answer:

The answer is C: if the value of x increases by 3, the value of y will triple which is FALSE

Step-by-step explanation:

looking at the answers and using the "gizmo" when clicking the view lab tab. After pluging in y=4*3^x, you'll see that the function does indeed decreases so

A: Ture

for b, again looking at the graph of simply inputting -4*3^0 you will get -4 which is (0,-4) so

B: True

for c, let's plug in the info... -4*3^3 will give us -108 which is showing a decreases and not an increase so

C: False

and just for fun of it, let look at d meow, again plug in -4*3^1 and we get -12 which is (1,12)

D: Ture

Plus I just took the test on 23 May 2o2o and C is the right answer... BOOM
