Algebra 1 A CBE Day 2

S = 3F - 24  Solve for F

• F = (S + 24)/3

• F = S/3 + 24

• F = 3S + 24

• F = 3(S + 24)

Solve:
y = mx + b , for b

• y - mx = b

• y + mx = b

• y/mx = b

• y + mx = -b

What is the definition of function?

• Has inputs and outputs

• Every input has only ONE output

• Inputs have different outputs every time
