Step-by-step explanation:

F(2)=3(2)²-7

=5

................

Answer:

Square 2. Multiply the result by -3, and then subtract 7.

Step-by-step explanation:

The answer is basically the explanation of the answer. You want to replace x with 2 then square it. You will have 4. Multiply 4 by -3 and you will have -12 then subtract it by 7 and you'll get the answer to f(x). The answer is the steps. Not the 'answer' answer. Hope this helps!
