If you solve equation f(x)=3x-2 by plugging in 2 and/or 4 for "x", what points do you use to graph?

Question

Any help is much appreciated.

Answer 1

x=2
y=3(2)-2
y=6-2
y=4
(2,4)

x=4
y=3(4)-2
y=12-2
y=10
(4,10)

Answer 2

if you have f(x)=3x-2 and your x is either 2 or 4, u just plug that into the equation and get your y coordinate and graph that point

for example,
if x=2 you would plug it in f(x)=3(2)-2 which is 4
so your coordinate point would be (2,4)

if x=4 you would plug it in f(x)=3(4)-2 which is 10
so your coordinate point would be (4,10)

you can continue plugging in x values in the equation and getting multiple y values that will help you graph it easier

Answer 3

Points

(2, 4)
(4, 10)

Answer 4

substitute:

let
f(x)=2

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