Question

Select the correct answer. If the function 5x + y = 1 has the domain {-2, 1, 6}, then what is the corresponding range? A. {-9, 6, 31} B. {9, -6, -31} C. {-11, 4, 29} D. {11, -4, -29}

Answer 1

The answer to your question is: letter D

Explanation:

Function

5x + y = 1

Domain {-2, 1, 6}

Process

Domain is the possible values of the independent variable.

Range is the values of the dependent variable.

Evaluate the function with each of the domain values to get "y"

When x = -2

5(-2) + y = 1

-10 + y = 1

y = 10 + 1

y = 11

When x = 1

5(1) + y = 1

5 + y = 1

y = -5 + 1

y = -4

When x = 6

5(6) + y = 1

30 + y = 1

y = 1 - 30

y = -29

Range = { 11, -4 , -29}
