Answer» If f(x) = X2 – 5 for all values x and f(a) = 4, what is one possible value of a?Possible Answers:1311814Correct answer:3Explanation:Using the defined function, f(a) will produce the same result when substituted for x: f(a) = a2 – 5Setting this equal to 4, you can solve for a:a2 – 5 = 4a2 = 9a = –3 or 3Report an ErrorFind F(X) : Example Question #2If the function g is defined by g(x) = 4X + 5, then 2g(x) – 3 =Possible Answers:4x + 28x + 78x + 26x + 76X + 2Correct answer:8X + 7Explanation:The function g(x) is equal to 4x + 5, and the notation 2g(x) asks us to multiply the entire function by 2. 2(4x + 5) = 8x + 10. We then subtract 3, the second part of the new equation, to get 8x + 7. |
