Question

i just need a,bDetermine whether the graph below is that of a function by using the vertical-line test. If it is, use the graph to find (a)its domain and range.(b)the intercepts, if any.(c)any symmetry with respect to the x-axis, y-axis, or the origin.

Answer 1

PART A

We can see that the domain is: [-π , π] and the range is: [-1,1].

PART B

We see that the x-intercept is at x=0.

We see that the y-intercept is at y=0.
