Question

given f(x)=3x-1 and g(x)=2x-3, for which value of x does g(x)=f(2)?

Answer 1

so we need to figure out what makes g(x) = f(2)
so we are given that for f(x) x = 2
so plug in x = 2 into f(x) = 3x-1 and see what number we have.. then we can find an x and plug it into g(x) to make
g(x) = f(2) true

Answer 2

so f(x) would = 7

Answer 3

wrong arithmetic. If f(x) = 3x+1
x = 2
f(2) = 3(2)+1=6+1=7
but we are given
f(x) = 3x-1
so plug x = 2 in the correct function .

Answer 4

so
f(2) = 3(2) -1 ?
we are subtracting

Answer 5

@tildax what is 6 - 1?

Answer 6

sorry just got back lol and 5 haha

Answer 7

it's alright lol
so f(2) = 5

so now we need an x for g(x) to produce 5

g(x) = f(2)
g(x) =5

Answer 8

g(x)=2x-3
what x value do we need to produce 5?

Answer 9

4

Answer 10

alright!
so when x = 4
g(4) = 2(4)-3 =8-3=5

so
g(4) = f(2)
5=5 :)
