Answer with Step-by-step explanation:
We are given that
We have to write the rule for function g and describe the transformation between f and g.
Compress the function by scale factor 3 and the translation rule is given by
Then, we get 
Now, shift the y coordinate 4 units above the origin.
Then, the translation rule is given by
Then , we get
To find the answer, we can first find the age of Rolando in four year:
17+4
=21
We can then proceed to find the current age of Marisa,which is 3/2 of Rolando’s age calculated above:
Let Marisa’s age be y.
3/2 y =21
y = 21 × 2/3
y = 42/3
y = 14
Therefore Marisa is currently 14 years old.
In three years, Marisa would be:
14+3
=17
Therefore, she will be 17 years old.
Hope it helps!
