Answer:
f(2) = 15
for f(x) = 4, x = 6
Step-by-step explanation:
f(2) means f(x) for x = 2.
in the table for x = 2 we see f(x) = 15.
the second question : f(x) = 4
so, where in the table do we find f(x) = 4 ? ah, for x = 6 do we find f(x) = 4.

Answer:
u = <3.5,2>
Step-by-step explanation:
u = 4<cos(30°), sin(30°)>
= 4<√3/2, 1/2>
= <2√3, 2>
≈ <3.5, 2>
