Which form of equation models the data if a is a negative integer and b is a positive integer? A. b = a x/y
B. y = ab^x
C. y = ax + b
D. y = ab^−x

c

Step-by-step explanation:

You can notove that this form makes sense

If we replaxe a by -2 abd b by 7 we get the data modeled in the graph

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

yes. we do proportions in probabilities.
