Question

If the domain of the function f(x)=2x2- 8is {-2, 3, 5}, then the range is

Answer 1

Answer:

{0, 10, 42}

Step-by-step explanation:

Domain is set of input values and range is set output values.

For the function f(x) = 2x² - 8 and domain set of {-2, 3, 5}

Range is:

• f(-2) = 2(-2)² - 8 = 0
• f(3) = 2*3² - 8 = 10
• f(5) = 2*5² - 8 = 42

Range: {0, 10, 42}
