Question

The graph of a quadratic function meets the x axis where the x=3 and x=k. if the turning point of the function occurs where x=0.5, find the value of x

​

Answer 1

Explanation:

The turning point of a quadratic function is equidistant from both x-intercepts (if they exist)

Since they do exist in this question, 3 + k = 2(0.5), 3 + k = 1, k = -2.
