Answer:
Step-by-step explanation:
x intercepts are -3,-1
f(x)=-(x²+x+3x+3)=-(x²+4x)-3=-(x²+4x+4-4)-3=-(x+2)²+4-3
or f(x)=-(x+2)²+1
vertex is (-2,1)
so it is an inverted parabola with vertex (-2,1) and x-intercepts (-3,0) and (-1,0)
Answer:
The answer is 17 and no
Step-by-step explanation:
#11 The room is a cube so...
cube root the volume 4913
³√4913=17
The length of the room is 17 feet.
#12
Square root 121
√121=11
Since the car is 13 feet the car will not fit in the garage which is 11ft.
Swapping rows alters the sign of the determinant:

Multiplying a single row by a scalar scales the determinant by the same amount:

Then
