The range of function is { -1, 1 }
<em><u>Solution:</u></em>
Given that, the function is:

Domain is {0, 2 }
We have to find the range of function
The domain refers to the set of possible input values
The range is the set of possible output values
Here domain is x = 0 and x = 2
<em><u>Substitute x = 0 in given function</u></em>

<em><u>Substitute x = 2 in given function</u></em>

Thus the range of function is { -1, 1 }
The volume of a cube is the side length cubed.
Volume of one cube = 2^3 = 8 cubic inches.
The tray has 14 cubes.
Total volume = 14 x 8 = 112 cubic inches.
Answer:
To find that a triangle can be made from these measurements you should know that the sum of two of its sides should be greater than the third side.
lets see if this rule applies...
9+9 = 18 ( greater that 17 ; its third side)
17 + 9 = 26 (greater than 9 ; its third side)
therefore, a triangle can be formed
as two of its sides are equal , it is an isosceles triangle
You wrote the equation wrong- he starts with 9 pencils so that's a constant and he sharpens 11 pencils for every minute. The equation would be 9+11x with x being the amount of minutes, which in this case is 7. So you just substitute and solve.
9+11x
9+11(7)
9+77
86
