Question

The one-to-one functions g and h are defined as follows. 8(x) = *713 h={(-9, 2), (-7, 7), (2, -8), (3, -3)} Find the following. x 6 ? (64.5)(2) = 0 n'(2) = 0

Answer 1

Solution : gtx) = - 13 4 = { t-q, d), (-1, 1), (+, - 0), Сэ, -30$. (1), " (x) = 9 ах, 2 cm) - у x- 13 = Пу х = 1 4 13. 1Г 1) — а ч) = || +13 Robtаtе чіку има лh, - 3 x ) = 1х +13| (8) » ( 9 ) се ? firestly, we (g! g) (x) ( 8 3) Сх) = -1 : 2 x)} = 3*(- 13 ) = (х - 13 ) +13 - К - 13 + 13

(glog)(x) = x (9og)() = 21 (ii) ei-'(&) = 9 h = {(-9,),(-7,7), (2,-0),(3,-3). = {(n, h(x)} . Let, x=2 hl= { la, ule) = {(2,-0)}. h-1 (22) = { ( 4 "(x), x)}. ( i n us one-to-one function). Thia) - g de el-9) = 2 2 1 -9 = ht(2).)
The concept is easy to understand as you can approach to a solution . Hope you can understand easily.
