The answer is either a or d but we know she did all of this for more than 52 minutes.
She can simplify the 12 and the 3.
The 3rd one
This is because in the graph it’s looking for numbers 70-79 but only with 2 numbers and the 3rd is the only one that fits in the description.
Answer:
g(x) = 
Step-by-step explanation:
Exponential function 'g' that can be written as g(x) = a.bˣ
From the graph attached,
Graph of the function passes through two points (0, 9) and (1, 3)
g(0) = a.b⁰
9 = a
Similarly, g(1) = a.b¹
3 = a.b
3 = 9(b)
b = 
Therefore function will be,
g(x) =
