Question

what is the answer to this question A function, f(x) = 4x + 5, has a domain 0 ≤ x ≤ 50. What is its range?

Answer 1

5 ≤ y ≤ 205

Explanation:

Input values 0 and 50 for x in the function f(x) - 4x + 5

Solve:

• f(0) = 4(0) + 5
• f(0) = 0 + 5
• f(0) = 5

• f(50) = 4(50) + 5
• f(50) = 200 + 5
• f(50) = 205

The range is between these two points: 5 ≤ y ≤ 205
