I'll do #6.

The axis of symmetry is the x-coordinate of the vertex, which in this case, is (0,-4). So the axis of symmetry is x=0.

The vertex is in the above answer. Since this is a quadratic function, there are no boundaries, the domain is All Real Numbers.

The range goes up forever from the vertex. The vertex is (0,-4), so, the minimum y value is -4. The range is y is greater than or equal to -4, or in interval notation: [-4,infinity]

Hope this helps!

Can anyone help me in this whole math question? Especially Number b and c. Thanks.

Answer:

Irregular polygons are polygons that do not have equal sides or equal angles. When finding the area of an irregular polygon, partition the polygon into smaller regular polygon shapes. You can then plug those measurements into their respective area formulas and multiply to find the area of one part of the shape.

This is 16cm.

Find the midpoint of the line segment with end coordinates of:(−1,7) and (3,−2)

SOVA2 [1]

Answer:

Step-by-step explanation:

mid point formula = (x1+x2/2 , y1+y2/2)

hence putt the values we get,

mid point = ( -1+3/2 , 7-2/2)

= (1 , 2.5)

Is 2/3 greater than 4/8

MArishka [77]

Find a common denominator to begin. The common denominator is the LCM of both denominators. In this case, the common denominator will be 24.

Now, multiply the numerator by the number you multiplied the denominator. For 2/3, you multiplied 3 by 8, so multiply 2 by 8 to get 16. The fraction is now 16/24. Multiply 4 by 3 since you multiplied 8 by 3 to get 24. You will get 12 and the fraction will become 12/24.

Then, compare. 16/24 is closer to 24/24, or one whole, so 16/24, or 2/3, is greater.
