WILL MARK BRAINLIEST!!! Your friend states that for functions of the form y = a sin bx and y = a cos bx, the values of a and b affect the x-intercepts of the graph of the function. Is your friend correct? Explain

Respuesta :

Answer:

The sine function won't be affected, but the consine function will.

Step-by-step explanation:

First of all, remember that [tex]sin(0)=0[/tex] and [tex]cos(0)=1[/tex]. As you can see, the sine function won't be affect by [tex]a[/tex], because its value is null.

However, the x-intercept of the cosine function depends on the [tex]a[/tex] value, because the function is equal to the unit.

On the other hand, the variable [tex]b[/tex] won't affect any function, because it would be always zero.

Therefore, the sine function won't be affected, but the consine function will.
