Answer: The correct option is (A).
Step-by-step explanation: Given that the equation of the quadratic parent function is
We are to find the equation of the new function after shifting the parent function (i) 12 units left.
Since we are shifting 12 units left, so there is a horizontal translation in the X-axis.
And the x co-ordinate becomes (x+12).
Therefore, the equation of the new function will be
Thus, the required equation of the new function is
Option (A) is correct.
The exponential function is given by
An exponential function is in the form:
Where a is the initial value of y and b is the multiplier factor
Let y represent the amount of drug after x hours.
After 2 hours, there are 32 mg left. Hence:
After 5 hours, there are 10 mg left. Hence:
From equation 1 and 2, b = 0.6786, a = 69.5
The exponential function is given by
At 1 hour:
y = 69.5(0.6786) = 47 mg

Answer:
(x, y) = (2, -5)
Step-by-step explanation:
The equation is of a line. There are an infinite number of points that will satisfy the equation.
Perhaps you are referring to the fact that the equation appears to be in point-slope form. That form is ...
y -k = m(x -h)
for a line with slope m through point (h, k).
In your equation, k = -5 and h = 2, so the line is known to go through point (2, -5) with slope 3.
