Question

Say whether or not f(x) is defined for the given values of x. If it is defined, give its value. HINT [See Quick Example 3.] (If an answer is undefined, enter UNDEFINED.) f(x) = ?(81 - x²), with domain (-9, 9) (a) x = 0 f(0) = 9 (b) x = 9 f(9) = -9 (c) x = -9 f(-9) =

Step 1

Step 1: To find f(0), we substitute x = 0 into the function f(x) = √(81 - x^2): f(0) = √(81 - 0^2) = √81 = 9 Show more…
