Use the form a cos(bx-c) +d to find the variables used to find the amplitude, period, phase shift and vertical shift.
a would be the amplitude and is the number before cos.
In the given formula -1/2 is before cos, so the amplitude would be the positive value which would be 1/2

Answer is -3</h3>
Explanation:
The leading term of a polynomial is the term with the largest exponent, which in this case that exponent is 4. So the leading term is -3x^4.
The leading coefficient is the coefficient of the leading term. The coefficient of the term -3x^4 is -3.
If the polynomial is written in standard form, then the process is as simple as reading the first coefficient. Otherwise, you may have to sort the terms out first.
X = -8
since you know that it’s a vertical line, it’s going to be x = _. since -8 is the x coordinate, the equation is x = -8. hope this helped!
