Question

Question 13 5 pts Determine whether the function is one to one or not: {(-3,-5) (-2,-4) (-1, -3) (0, -2)(-1,-1) (-2, 0) (-3, 1)} Yes No, it is not one to one Oo oo Not a function None of the above. 5 pts Question 14 Find the inverse of the function: f (x) = x3 + 13 f'(x) = V2 - 13 y=2-13 33 = 2 - 13 None of the above.

Answer 1

13 thar not a we can norice the element ins' of the domain the codomain Ber is assigned to distincer rates of bet (ie. a5 and 1) so, this is function, ① Güven that, fex) = x² +13=4 (say) => x- Y-13 => x= 34-13 now by entire changing in and y get, x-13 ic. I f-'(x) we 01-13

(15 fix) = {)X soft-3) (4) 525 f(-1)-(5)-51-5 f(0) = ()= f(1) = (+) = 1/5 fiz) < (+)= has 1 50, second option is connect 17 The amount will be, A= *2 (142093 (1-01) 19} $ 312000 x * $ 19,346.71 of the above None 0 so connect option is

② log2x + log2 (x-2) =3 => log₂ (2²-2x) = 3 o x², 2x = 23 >> 22-2x = 8 -> W224-820 -> *2- Axe + 2X-8=0 >>x6x-1)+2(x-4)=0 ->(x+2)(2-1) = 0 => x=-2 om, as log (-ve) is not defined, thind option as 4 80 we have a=4 Bur 30, connect
