What can you say about the continuous function that generated the following table of values?

a. the function has exactly one x-intercept
b. the function has more than one x-intercept
c. not enough information to answer the question
d. the function has no x-intercepts

Every time the function changes sign, it crosses the x-axis, which means an x-intercep. Aslo when the value of the function is zero it is an x-interceot.

The tables shows two changes of sign (from +4 to -3 and from -3 to +2). It also has one zero value, then this function has at least three x-intercepts. And you can conclude that the choid b is true.

the function has more than one x-intecept.

When two lines intersect, they form two pairs of equal angles, which, taking one of each, add up to 180°. (jargon: angles forming a straight line   show more
