The range of y = x^2 is the set of nonnegative numbers. The same applies to y = 2x^2 as well. Shift everything up three units to get y = 2x^2+3
So the range is the set of numbers y such that
The final answer is choice C.

If the perimeter of a triangle is 19 cm. The lengths of 3 sides is: a = 8, b = 7, c = 4.
<h3>Parimeter</h3>
Let a = longest
Let b= shortest
Let c= third side
a = 2c
a = (b+ c) - 3
a + 3 = b + c
Using three variables to solve the expression for perimeter
Perimeter= 19 cm
a+ b + c = 19
a + (a + 3) = 19
2a + 3 = 19
2a= 16
Divide both side by 2a
a=16/2
a = 8
a = 2c
8 = 2c
c=8/2
c = 4
a + b + c= 19
8 + b + 4 = 19
12 + b = 19
b=19-12
b = 7
Hence,
a = 8, b = 7, c = 4
Therefore If the perimeter of a triangle is 19 cm. The lengths of 3 sides is: a = 8, b = 7, c = 4.
The complete question is:
Perimeter of triangle is 19cm. If the length of the longest side is twice that of the shortest side and 3 less than the sum of the lengths of the 2 sides find lengths of 3 sides.
