Question

if f(x)=2x+3, f(0)=? I need some help jogging my memory

Answer 1

remember that f(x) simply means "the function "F" of the given "x"

Answer 2

if you are looking for the f(0) then you need to replace the variable x with a 0 in your initial equation

Answer 3

so fill in what you know. the x here is 0. substitute and solve

Answer 4

so f(0)=3

Answer 5

yep

Answer 6

f(0)=2(0)+3
f(0)=0+3
f(0)=3
y=3
