Question

The table of values below represents a quadratic function. Between which two values of x will the quadratic function, f(x), have a zero?

x 2 5 8 11 14
f(x) -2 -5 10 43 94

Answer 1

Between (5,-5) and (8,10)

Explanation:

Because 0 is between -5 and 10, then there has to be a zero between (5,-5) and (8,10) for the quadratic function f(x) since you pass the x-axis in between.
