Hey there!

RANDOM FACTOID:

‘‘f(x)’’ or ‘‘g(x)’’ is understood to be “y”


f(x) = 2x

f(x) = 2(3)

f(x) = 2 + 2 + 2

f(x) = 4 + 2

f(x) = 6


Therefore, your answer is: f(x) = 6


g(x) = 5x

g(x) = 5(3)

g(x) = 5 + 5 + 5

g(x) = 10 + 5

g(x) = 15


Therefore, your answer is: g(x) = 15


OVERALL ANSWER: f(x) = 6 or g(x) = 15


Good luck on your assignment & enjoy your day!
