5. A function is given below.<br> f(x) = 3x2 - x + 6<br> What is f(2)?<br> 2
prohojiy [21]

Answer:

f(2)=16

Step-by-step explanation:

f(x) = 3x^2 - x +6   If you notice what the 2 is replacing in f(2) then replace it in the equation:

f(2) = 3(2)^2 -2 +6    Use the order of operations to solve (PEMDAS)

f(2) = 3(4) - 2 + 6

f(2) = 12 - 2 + 6

f(2) = 12 + 4

f(2) = 16
