Option #1:
f(4), this means that x = 4
To find f(4), substitute/plug in 4 into "x" in the function:
Plug in 4 into "x" since x = 4
f(4) = 2
Option #2:
f(4), this means that x = 4
To find f(4), substitute/plug in 4 into "x" in the function:

Actually, the answer is not A, if you're saying A is the first choice above. That's incorrect. You will need to use the Geometric mean for right triangles here to figure out what the value of a is. We will use this form:
. We have a value for YZ of 3; side a is XZ. That means in order to solve this we need WZ, which we can find using pythagorean's theorem. 3^2 + 4^2 = c^2 and 9 + 16 = c^2 and c = 5. Now we fill in accordingly:
. Cross-multiply to get 3XZ=25 and side XZ is
. XZ is 25/3 and YZ is 3, so 25/3 - 3 = XY. That means that XY (side a) = 16/3 or 5 1/3, choice B, or the second one down.
