What can you say about the continuous function that generated the following table of values? -3 0 -3 O A the function has more than one x-intercept O B. the function has exactly one x-intercept O c. the function has no x-intercepts O D. not enough information to answer the question

Solution

This is a tricky one...

Clearly there is an x-intercept at x = 5.
So, this eliminates option C.

But we need to check and see if it may have more x-intercepts....

Look at the table of values.
When x = 0 , y = -3
And when x = 1 , y = 2

This means, somewhere between x = 0 and 1, the curve must have crossed over from negative side to the negative side, right?

This gives us another x-intercept somewhere between x = 0 and x = 1.

Similarly, there is another x-intercept between x = -3 and x = 0

So, clearly, more than 1 x-intercept

Option A
