Function of the Day: y = .75x - 3. Complete the table for the given function. x = -2, 0, 2, 4.
x = -2, y = -4.5;
x = 0, y = -3;
x = 2, y = -1.5;
x = 4, y = 0.
x = -2, y = -5;
x = 0, y = -3;
x = 2, y = -1;
x = 4, y = 1.
x = -2, y = -4;
x = 0, y = -2;
x = 2, y = -1;
x = 4, y = 1.
x = -2, y = -4.5;
x = 0, y = -2.5;
x = 2, y = -1.5;
x = 4, y = 0.5.
Function of the Day: y = .75x - 3. Find f(5) and the y-intercept.
f(5) = 0.75(5) - 3 = 0.75;
y-intercept = -3.
f(5) = 0.75(5) - 3 = 1.75;
y-intercept = -3.
f(5) = 0.75(5) - 3 = 0.75;
y-intercept = 3.
f(5) = 0.75(5) - 3 = 1.75;
y-intercept = 3.

Function of the Day: y - 4 = -0.5(x + 3) Find f(5) and the y-intercept.
f(5) = -0.5, y-intercept = 4
f(5) = -3.5, y-intercept = 2.5
f(5) = -2.5, y-intercept = 3
f(5) = -4, y-intercept = 1

An airplane’s altitude in feet during its descent can be found using the function f(x) = -200x + 20,000. After new government regulations become law the descent is now modeled by the function g(x) = -200x + 20,500. Which statement describes this change?
The airplane starts its descent from an altitude 500 feet higher.
The airplane starts its descent from an altitude 500 feet lower.
The airplane descends 500 feet per horizontal mile faster.
The airplane descends 500 feet per horizontal mile slower.
