QU 10 ii) sketch the inverse of f(x) tht is reflection on y=x

iii) let f(x) = y
make x subject of formula
then f inverse = the equation in terms of y but replace the y by x
do this for both equations

as for the set of values
range of f(x) = domain f inverse
domain of f(x)= range of f inverse
whn sketching the graph ull find it

its -5<x<1 and 1<x<4 as far as i remember...i did it this morning

QU 11
replace c by 11 on line
solve curve n line simultaneously...ull get x coordinates
integral of line - integral of curve
solve for limits which are the x coordinates found whn solved simultaneously
put modulus if it becomes negative

Guys is it acceptable to multiply 2^x (into) 3^x to be 6^x ??

Yes.

I am not sure whats in that pic, but Rutzaba will tell you after looking into it.. btw its 6x^2

 

[Thought blocker]

Yes.

Come on! Really?

 

[Kamihus]

Come on! Really?

Didn't check the question, just said that 2^x*3^x is 6^x. Just Plug in some values to make sure.

Yeah...It's like (2 X 3)^x
