Question

Dependent variable:
2. Find the range of the function f(x) = 2x + 7 for the domain (-2,3,8).
Range:

Answer 1

Given f(x) = 2x + 7, you can plug in the domain values into linear function to find the range:

f(-2) = 2(-2) + 7 = = -4 + 7 = 3
f(3) = 2(3) + 7 = 6 + 7 = 13
f(8) = 2(8) + 7 = 16 + 7 = 23.

Therefore, the range is {3, 13, 23}.
