Answer:
d. None of the above.
Step-by-step explanation:
The period is the change in x required to make a change of 2π in the argument to the sine function:
2x = 2π
x = π
The frequency is the reciprocal of the period, so is 1/π. There are no matching answer choices.
When dealing with a quadratic equation, you usually assign the following name to the coefficients of the variables:
So, is the coefficient of , is the coefficient of and is the constant term.
In your case, the coefficient of is -3, so
The coefficient of is -2, so
The constant term is 6, so
1 1/8
3/4 = 6/8 ( 3x2= 6 numerator ) ( 4x2= 8 denominator )
6/8 + 3/8 = 9/8 = 1 1/8
