First let you know what to do. OK. Going to drag a ruler. Across the paper. Vertically. And if it touches 2 points on the grid. Then it fails the test.
Hi there!
Let's solve this problem step by step!

To find f(3) we must substitute x = 3 into the formula.

Now we use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Work out the exponents inside the parenthesis first.

And finally multiply.

Hence, the answer is D. 64.

I think it’s B or A But I’m not sure
Well, Doing 8,600 x .0395, you get 339.7, then if you do that x 25, that's too low if you add 8600 to it, 36 years if you do 339.7 x 25, then add 8600 its extremely close to 21000. And since you put approximately, since this will round up, the best answer choice is definitely B
Hope this helps. Have a great day!
