Question

Evaluate the function at the indicated values. (If an answer is undefined, enter UNDEFINED.) f(x)=x²−2;f(−3),f(3),f(0),f(21​) f(−3)= f(3)= f(0)= f(21​)=

Answer 1

To evaluate the function f(x) = x²−2 at the given values, substitute the values into the function and simplify.

Step-by-step explanation:

To evaluate the function f(x) = x²−2 at the given values, we substitute the values into the function and simplify.

f(-3) = (-3)² - 2 = 9 - 2 = 7

f(3) = (3)² - 2 = 9 - 2 = 7

f(0) = (0)² - 2 = 0 - 2 = -2

f(21) = (21)² - 2 = 441 - 2 = 439

Therefore, f(-3) = 7, f(3) = 7, f(0) = -2, and f(21) = 439.
