Answer:
The domain is all real numbers.
The range is all real numbers.
The graph crosses the y axis once.
The graph increases from negative infinity to positive infinity.
Step-by-step explanation:
The graph crosses the axis when x = 0:
y(0) = (0 - 3)^3 + 1
= -27 + 1
= -26 so it crosses y-axis at (0, -26) only.
Point where it crosses the x axis is when y = 0:
(x - 3)^3 + 1 = 0
(x - 3)^2 = -1
x-3 = cube root of -1 = -1
x = 2. It only crosses the x axis once at (2, 0>
Focus at(7,-11)
- x>0,y<0
- Lies in 4th quadrant
Equation of directrix y=-3
So what can be told?
Equation of parabola
Answer:
x = 3
Step-by-step explanation:
We can tell the two pictured angles are equal because they have the red lines showing they are equal. Because of this we can set up the following equation and solve
(for your info, all numbers without x in the steps have °, but for the sake of time left them out)
<em>(equation)</em> 2x + 5 = 7x - 10
<em>(subtracting 2x from both sides & adding 10 to both sides)</em> 15 = 5x
<em>(dividing both sides by 5) </em>3 = x
Hope this helps, have a nice day :D
<u>Answer:</u>
Supplement of 84° is 96°
Complement of 54° is 36°
<u>Step-by-step explanation:</u>
1<u>) A supplementary angle is two angles that add up to 180°</u>
so to find the supplement of 84° ⇒ 180°- 84° = 96°
2) <u>A complementary angle is two angles that add up to 90°</u>
so to find the complement of 54° ⇒ 90°- 54° = 36°
The answer is m = r/(k+q).
