Answer: The function could be y= - 3 cos x
Solution:
One x-intercept is (pi/2,0): We can use a trigonometric function like cosine that has x-intercept (pi/2,0).
The domain of the cosine function is the set of all real numbers.
The maximum value is 3, then the amplitude must be 3: y = 3 cos x
The y-intercept is (0,-3) then it is the functio y = 3 cos x, reflected around the x-axis: y = - 3 cos x
Answer:
$1.92
Step-by-step explanation:
To find the cost per bag we divide the total cost by the amount of bags so:
$5.75 / 3 = $1.91666667 per bag, which we can round up to $1.92 per bag.
