9. let x = {1, 2, 3}, y = {1, 2, 3, 4}, and z = {1, 2}. a. define a function f : x → y that is one-to-one but not onto. b. define a function g: x → z that is onto but not one- to-one. c. define a function h: x → x that is neither one-to-one nor onto. d. define a function k: x → x that is one-to-one and onto but is not the identity function on x.

congruent segments

step-by-step explanation:

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
