What are the solutions to the system of equations?

*No spaces, write the word "and" inbetween the two points.

Write the solution set for each of the quadratic inequalities. Use a capital "E" for
, "inf" for
, and do not put any spaces.

The inverse of a function is always a function.

Look at the table of values between the number of hour a person works in a week and their overall happiness with their job on a scale from 1 to 100.

The equation of any parabola is

is the vertex and
is the distance between the focus and the vertex. If the vertex is
and the focus is
, what's the equation of the parabola in this form?

Consider the equation:

This equation represents the height of an object at a given time going a specific velocity (speed).

is the height of the object at a specific time,

is the velocity of the object at the start of it's movement

is the height the object starts at
