Answer
We can easily see that the relationship between x and y is exponential.
Explanation
We can see from the table that as we move a unit of x towards the right, the values of y are multiplied by 2.
So, we can see that the relation is of the form
y = 0.75 (2ˣ⁺²)
when x = -2, (x + 2) = -1 + 2 = 0
y = 0.75 (2⁰) = 0.75 (1) = 0.75
when x = -1, (x + 2) = -1 + 2 = 1
y = 0.75 (2¹) = 0.75 (2) = 1.50
when x = 4, (x + 2) = 4 + 2 = 6
y = 0.75 (2⁶) = 0.75 (64) = 48
Hope this Helps!!!
