Question

f(t)= {-64/t , t=8 {14-t , t=10 {t^2-3t+2 , t= 8,10

Answer 1

For this type of questions we have to find to which part of the domain the number 2 belongs to, notice that 2 is different from 8 or 10 then we must apply the definition of the function for

`t\\e8,10`

Susbtituting t=2 we get:

`f(2)=2^2-3(2)+2=4-6+2\text{ = 0}`

Answer: f(2)=0.
