Question

Evaluate the following expressions given the functions below:

t(x) = -4(x + 12)
Let: t(a)

Answer 1

Answer: t(a)= -4a - 48

Explanation:

Just plug a into x so you'll get: t(a)= -4(a + 12)

Then simplify it: t(a)= -4a - 48

If it says let t(2) then you will plug 2 into x=> t(2)= -4(2 +12)

which equals to t(2)= -8 -48

t(2)= -56

Hope this help
