Question

help!
Using a table, find the range of the function for the given domain:

f(x)=−x−12 with domain: x = {-5, -4, -3, -2}
A. y = {5, 4, 3, 2}
B. y = {-3, -2, -1, 0}
C. y = {1, 2, 3, 4}
D. y = {-7, -8, -9, -10}

Answer 1

It’s D just plug in the x values to the equation

Answer 2

The required range of the function f(x)=−x−12 with domain is  x = {-5, -4, -3, -2} is y = {-7, -8, -9, -10}. Option D is correct.

Using a table, to find the range of the function for the given domain: f(x)=−x−12 with domain: x = {-5, -4, -3, -2}.

What are functions?

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is independent variable while Y is dependent variable.

Putting value of domain: x = {-5, -4, -3, -2} in f(x)=−x−12
x = -5
f(-5) = -(-5) - 12
f(-5) = -7

similarly,
f(-4) = 4 - 12
     = -8
f(-3) = 3 - 12
f(-3) = -9
f(-2) = 2 - 12
f(-2) = -10
Range (y) = {-7, -8, -9, -10}

Thus, the required range of the function f(x)=−x−12 with domain is  x = {-5, -4, -3, -2} is y = {-7, -8, -9, -10}. Option D is correct.
