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>

Its the same this as before you start by writing it out how the way PEMDAS works. PEMDAS is ( Parenthesis, Exponents, Multiplication, Division, Adding, and Subtraction). Also i accidentally messed up my other answer so give me a sec.
