Which of the following statements will have the same result? Explain each step in solving each one
f(3) when f(x)=2x+2
f^-1(4) when f(x) = 3x-4/5
y+10=2y+1
@Mertsj can you help me :)
f(3) for the first one is 8
In the second one, f inverse is(1/3)x + 4/15 so f^(-1)(4)=4/3 + 4/15=20/15+4/15=24/15=8/5
I'm not sure what you mean by the third one because it simplifies to y = 9
Hmm yeah so none of them equal to the same thinggg
and where did you get 15 from?
You need to check out the third one. I think it might be posted incorrectly. Isn't it supposed to have an x in it?
1/3 times 4/5 = 4/15
no its y + 10 = 2y + 1
Then none of them have the same result.
and for the second dont you have to change f(x) to y and change the x and y
yes
y=3x-4/5 x=3y-4/5 x+4/5=3y (1/3)x+4/15=y
@Mertsj When I explain the 2nd one can I say sub. 4 into x..cause the answer comes out to 8/5 still
yes
