Question

Let f(x) = 1 2 x + 3.

Give a quadratic function whose fixed points are x = −2 and x = 3.

Answer 1

If you have x = −2 and x = 3, then the factors would be (x + 2) and (x - 3)

Multiply these to get a quadratic expression.

Given the above logic, what is the relevance of the first statement?

"Let f(x) = 1 2 x + 3."
