4t ^ 2 - 16 ÷8 ÷ t - 2 ÷6
=(4t ^ 2)-(16 ÷8 ÷ t)-(2 ÷6)
=(4t ^ 2)-(2/t)-1/3
=4t ^ 2-2/t-1/3
Answer:
13
Step-by-step explanation:
f(-2) means you want to find the y value when x=-2. Plug in x=-2 into the f(x) equation to get: [-3(-2)]-2 = 6-2 = 4.
so f(-2)=4
But the question asks for f(-2)+9. So you add 9 to f(-2) which is 9+4 = 13
im pretty sure you got it right with 40!!
