Answer:
334.488
Step-by-step explanation:
I used a calculator lol
g(x) - f(x) = x^2 - 9 - (2 - x^1/2)
= x^2 + x^1/2 - 11
negative x gives no real value for this function because x^1/2 is not defined for negative x
the domain is x >= 0 or in interval notation [0, ∞)
Im going to guess you want a sinusoidal function. Its been a while but I can tell you most of it
(443-28)/2 is the amplitude
28 minutes is the period
40-28 is the horizontal shift
(443-28)/2+28 is the vertical shift
Answer:
Reflecting a point across the y-axis -> changes the sign of the x-coordinate
Reflecting a point across both axes -> changes the sign of both coordinates
Reflecting a point across the x-axis -> changes the sign of the y-coordinate
Step-by-step explanation:
Reflections:
- The rule to reflect a point across the y-axis is (-x, y), meaning that the x-coordinate's sign changes.
- Reflecting a point across both axes is the same thing as rotating it 180 degrees, so the rule is (-x, -y). This means that both coordinates' signs change.
- Reflecting a point across the x-axis is (x, -y), meaning that the y-coordinate's sign changes.
