Hello!
A cubic function is in the form of 
.
All cubic functions have a domain of all real numbers, the range also has a range of all real numbers.
Interval notation is used for representing a function/interval as a pair of numbers. Parentheses and brackets are used to show if the endpoints of a given function/interval are included or excluded. Brackets allow the endpoints to be included while parentheses exclude the endpoint.
Our first instinct would be that the domain is written as [-∞, ∞], but that is incorrect. Infinity is not a number, but it is a concept. This means that they are excluded from the domain.
Therefore, the domain of the function f(x) is (-∞, ∞).
Answer:
1.5 cookies if 2/8 is like 2 cookies out of 8, 1/16 if its like 2/8 of a cookie
Step-by-step explanation: \
1.5: 2 x 3/4 (already ate 1/4) = 1.5
1/16= 1/4 (2/8 reduced) x 1/4
Answer:
The triangle is obtuse.
It is an isosceles triangle.
The angles add up to 180°.
Step-by-step explanation:
Obtuse triangles are defined as triangles with one angle obtuse angle over 90°. This triangle has an angle of 100°, so it is an obtuse triangle!
Isosceles triangles have 2 equal sides. The two orange dashes on the left and right legs of the triangle tell us they are equivalent, so this is an isosceles triangle as well!
Finally, <em>all </em>triangles add up to 180°! We can prove this by adding the angles.
40° + 40° = 80°
100° + 80° = 180°

Step-by-step explanation:
The equation can be written in slope-intercept form as ...
y > -3x +4
The dashed boundary line has a y-intercept of (0, 4) and a slope of -3. Shading is where x-values and y-values are greater than those on the boundary line, so will be to the right and above the line.
34.49 cubic centimeters
Here is the math
(4/3)•(3.14)•(2cm)^3= (4/3)•(3.14)•(8)=34.49 cubic centimeters
