1. (a) What is the difference between a relation and a function?
(b) How can you determine if a relation is a one-to-one function? Give two reasons

Function h is defined by h(x) = 3 x 2 - 7 x – 5. Find h(x - 2).

Functions f and g are defined by f(x) = - 7 x - 5 and g(x) = 10 x – 12. find (f + g)(x)
In (9) above find f(1)/g(2).

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
