The graph of the function y=tan(x) was horizontally stretched so that its period became 10 pi. which is the equation of the transformed function?

is the equation of transformed function.

Step-by-step explanation:

The graph of the function y=tan(x) was horizontally stretched so that its period became 10π

First we draw the graph of y=tan(x)

Period of tan(x) is π

We need to change period of y π to 10π by horizontal stretch.

Therefore, y=tan(ax)

where, a is horizontal stretch.

Period of y=tan(ax) is 10π

When function change y=tan(x) to y=tan(ax)

Period change π to

New function after horizontally stretched by factor of 10 would be

Please see the attachment of graph and horizontal stretch.

Thus, is the equation of transformed function.

the 4th choice is the correct one

step-by-step explanation:

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
