Question

What is the range of the function f(x)=-3x-5 with a domain of {-3,0,11}

Answer 1

Answer:

R = {4,-5,-38}

Step-by-step explanation:

We know that the domain is the x value, meaning that the range is the y value.

f(x) = -3x - 5 is also y = -3x - 5

ur To find y(range) we need to solve the equation. Since we already have our x-values of {-3,0,11} all we need to do is plug in the values for x and solve.

I think you know the process of how to for y if you plug in these domain numbers, but if you don't, here is how to do it.

y = -3(-3) - 5             y = -3(0) - 5                     y = -3(11) - 5

y = 9 - 5                   y = 0 - 5                           y = -33 - 5

y = 4                         y = -5                               y = -38

Hope this helps!
