is it f(x) = -3x+4 or f(x) = -3+4x?
OpenStudy (anonymous):
idk.. its the question excact how i see it
geerky42 (geerky42):
Pretty sure it's \(F(x) = -3x+4\)
geerky42 (geerky42):
There is x after "-3," right? @Swordsman1305
OpenStudy (mindblast3r):

yeah ^ but I'm not going to outright blast the answer on here
OpenStudy (anonymous):
OOOH!! YOUR RIGHT.. I DIDNT TYPE IT!!!
OpenStudy (anonymous):
its x after the 3
OpenStudy (anonymous):
sorreh
OpenStudy (usukidoll):
since f(2), x = 2... you plug x =2 into -3x+4

knew it, it just proves that we got the skills to detect that it doesn't make sense
OpenStudy (anonymous):
lol
OpenStudy (usukidoll):
f(x) = -3x+4 .. since you are given f(2)
f(x) => f(2) implies that x = 2
plug in 2 into the function
OpenStudy (anonymous):
so c?
OpenStudy (usukidoll):
yeah

f(2) = -3(2)+4 = -6+4 = -2
