Question

Given: F(x) = 5x - 6 and G(x) = x - 4

Answer 1

i need help

Answer 2

what we need to do?????????

Answer 3

find f*g inverse

Answer 4

f(g(x)) inverse
u mean????

Answer 5

yes that

Answer 6

or just we need to multiply them

Answer 7

just multiply them

Answer 8

Given: F(x) = 3x 2 + 1, G(x) = 2x - 3, H(x) = x

Answer 9

(5x-6)(x-6)=5x^2-6x-30x+36=5x^2-36x+36

Answer 10

let y=5x^2-36x+36

Answer 11

now before doing inverse

Answer 12

f(x)=y=x^2+1
how we find inverse

Answer 13

just find value of x
y-1=x^2
(y-1)^1/2=x
now for inverse just switch x and y

Answer 14

y=(x-1)^1/2 is your inverse

Answer 15

do same for our prob

Answer 16

find value of x
y=5x^2-36x+36
5x^2-36x+36=y
5x^2-36x+36-y=0
using quadratic formula\[\frac{ 36\pm \sqrt{36^2-4*5*(36-y)}}{ 10 }\]

Answer 17

that is the value of x

Answer 18

\[x=\frac{ 36\pm \sqrt{576+20y} }{ 10}\]

Answer 19

on switching

Answer 20

\[y=\frac{ 36\pm \sqrt{576+20x} }{ 10 }\]

Answer 21

it is our inverse

Answer 22

similarly do for other
