Question

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

Answer 1

Answer:

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

Step-by-step explanation:

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

However, the x-intercept of the cosine function depends on the $a$ value, because the function is equal to the unit.

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

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