Question

What are the apparent zeros of the function graphed above. (-0.7, -2,7)

Answer 1

The zero of the function on the range (-0.7,-2.7) is {-2}

Explanation:

The zeros of a function can be determined graphically and are the points where the graph intercepts the x-axis, that is, where the value of y is zero.

In this case we can see that the three points where the graph cuts to the x-axis are {-2,1,4}.

However if we evaluate the zeros of the function in the range writen on your question, the zero of the function in the range (-0.7, -2.7) would be only the number {-2}

Answer 2

x ∈ {-2, 1, 4}

Explanation:

The graph shows y = 0 when x = -2 or 1 or 4. Hence these values of x are the zeros of the function.
