Answer:
it's the first graph
Step-by-step explanation:
I just did the Unit Test 7 part 2: Exponential and Radical Functions and got a 100%
oh and for the exponential growth question that is similar to this one, that's also the first graph.
The exponential function from the table is y = 32(0.5)ˣ.
Exponential function
An exponential function is given by:
y = abˣ
where a is the initial value of y at x = 0, y, x are variables and b is the multiplication factor
From the first table, we can see that the value of y decreases 50% each time. Using point (1, 16):
16 = ab¹
ab = 16 (1)
Also point (2, 8):
ab² = 8
a = 32, b = 0.5
The exponential function from the table is y = 32(0.5)ˣ.
