I only see part a, so for that one:
f(x) = 2x says that you’ll take your input (your x-value) and multiply it by 2 to get your output (your y-value).

f(7) = 2•7
f(9) = 2•9
f(-11) = 2•(-11)
f() = 2•

In part a, you’re asked for f(2), so this becomes :
f(2) = 2•2
= 4

Answer:

w = 5

Step-by-step explanation:

In the given right triangle, by trigonometric ratio, we have:

$\tan \: 60 \degree = \frac{5 \sqrt{3} }{w} \\ \\ \sqrt{3} = \frac{5\sqrt{3}}{w} \\ \\ w = \frac{5 \cancel {\sqrt{3}} }{ \cancel {\sqrt{3}} } \\ \\ w = 5$
