NASCAR Revenue. Action Performance Inc., the leading seller of NASCAR merchandise, recorded $260 million in revenue in 2002 and $400 million in revenue in 2004. Calculate the midpoint to estimate the revenue Action Performance Inc. recorded in 2003. Assume the horizontal axis represents the year and the vertical axis represents the revenue in millions.
1.1 and 1.2 Notes Summary Domain: the set of all x values (↔) Range: the set of all y values (↕) (To find domain of a function set the denominator equal to zero and solve, to find the range set the top equal to zero and solve.) X- Input // Y – Output Function: X value has only one Y value A function can be represented in a table, on a graph, and algebraically with a formula. A function must pass the Vertical Line test (VLT) to be considered a function. This means if a set of vertical lines is drawn and then function intersects a single line more than one, it fails the VLT. However, if it does not intersect, it passes. Even function: f(-x) = f(x) for f(x) Symmetric to Y - Axis Odd Function: f(-x) = -f(x) Symmetric to Origin Increasi
