The function f is defined by f x = 3x + k, where k is a constant. Find the value of k if the graph of f passes through the point (−1, 8).
Question
Solution 1
To find the value of k, we can substitute the given point (-1, 8) into the function f(x) = 3x + k.
So, we replace x with -1 and f(x) with 8:
8 = 3(-1) + k 8 = -3 + k
To isolate k, we add 3 to both sides of the equation:
8 + 3 = k k = 11
So, the value of k is 11. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study problem. Knowee AI StudyGPT is a
