Which of the following are true of f(x)?

f(x) is read as “f of x”
f(x) is the horizontal distance on the graph.
f is the graph at a particular value of x.
f(x) is a whole number.
y is equal to f(x)

a

step-by-step explanation:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
