Answer:
(-1, -4)
Step-by-step explanation:
The critical point is the point where the slope is 0 or undefined.
This is a parabola (quadratic), so there wont be any undefined points, only a critical point where slope is 0.
We need to take the derivative of the function and set it equal to 0 to find the x coordinate of the critical point. Then we plug in that x point into original equation to find the y coordinate.
Lets see the power rule of differentiation before we differentiate this function.
Power Rule:
Also, differentiation a constant is always 0!!
Now, differentiating:
Now, we set equal to 0 and find x:
Now, we find y:
So,
x = -1
y = -4
<u>The critical point is (-1, -4)</u>
Answer:
For example, a multiple of 2 is 2, 4, 6, 8, etc...
So if your question is find three multiples of 36, it would 36, 74 and 110.
Hoped this helped, have a nice day!

B) ABCD is a rhombus as all the sides are congruent (equal)
Answer:
x
Step-by-step explanation:
The 3 inside angles of a triangle need to equal 180
Now we can add all 3 angles and solve for x:
2x +x +60 = 180
Add 2x and x to get 3x
We now have 3x +60 = 180
Subtract 60 from each side:
3x = 120
Divide both sides by 3 to get x
x = 120/3
x = 40
Since angle b = x, angle b = 40 degrees
Angle a = 2x , so angle a = 2 *40 = 80 degrees
