Determine whether each of these functions is a bijection from r tor.

a) f(x) = -3x + 4
b) f(x) = -3x2 +7
c) f(x) = (x+1)/(x+2)
d) f(x) = x5 +1"

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
