Jenny was asked to identify the domain of the graph. she said the domain is [-4,♾). is jenny correct?

a. jenny is incorrect. the domain is [-1,3] because the graph crosses the x axis at -1 and 3.
b. jenny is incorrect. the domain is (-♾,♾) because the lines will continue to the left and right forever.
c. jenny is correct because the graph starts at -4 and goes all the way to the top
d. jenny is correct because the graph has both positive and negative values

ANSWER

b. Jenny is incorrect. The domain is (-∞,+∞) because the lines will continue to the left and right forever.

EXPLANATION

The graph is a parabola that continue to the left and right forever.

The parabola is a polynomial function of degree 2.

We know that all polynomial functions are define for all values of x.

The domain is the set of values for which the given function is defined.

Hence the domain of the given function represented by the graph is all real numbers.

We can write this as:

The correct choice is B.
