Slide 18:

Essential Question How do we represent functions
using function notation? MM1A1.a

Slide 19:

Let's begin by looking at
function notation.

Slide 20:

The following equations are
written in function notation. y(x) = 2x + 3 y = 2x + 3 b = 2a + 3 b(a) = 2a + 3 y in terms of x b in terms of a

Slide 21:

y(x) = 2x + 3 y = 2x + 3 b = 2a + 3 b(a) = 2a + 3 Make a note, the function variable in red can
be anything but, to remain consistent for this
lesson, we will use the variable provided.

Slide 22:

The following equations are
written in function notation. y(x) = -4x - 1 y = -4x - 1 s = 0.5t + 1.5 s(t) = 0.5t + 1.5 y in terms of x s in terms in t

Slide 23:

g(a) = -a + 10 This notation,
g(a), indicates
we have a
function. These two must
be the same
variable. This variable
can be
anything.

Slide 24:

Now, you do one.
Write the equation p = 3q - 6
in funtion notation. Is there only one right answer?

Slide 25:

Try these... Is there only one right answer? 1) c = -2b + 4
2) g = 4f - 1
3) x = -w + 5

Slide 26:

Try these... Is there only one right answer? 1) z = -2y + 4
2) e = 4d - 1
3) q = -p + 5

Slide 30:

The Anderson Family is comparing
the costs of two different satellite
companies. With plan A, equipment
installation is $199, and the monthly
fee is $29. With plan B, the
installation is $100, and the monthly
fee is $50. Write the function rule for
both plans. Plan A is s(m) = 29m + 199
Plan B is s(m) = 50m + 100

Slide 31:

The directions on the label of a
ham tell you to cook the ham 45
minutes per pound.
