Answer:
See explanation
Step-by-step explanation:
The question is incomplete, as the function is not given.
However, I will give a general rule.
From the question, we understand that the question requires the value of h(3)
Assume:
[tex]h(t) = 20 - 4t[/tex]
Then:
[tex]h(3) = 20 - 4*3[/tex]
[tex]h(3) = 20 - 12[/tex]
[tex]h(3) = 8[/tex]
