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

Step-by-step explanation:

First of all, remember that and . As you can see, the sine function won't be affect by , because its value is null.

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

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

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

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
