5-4: Writing a Function Rule
... You will write function rules to describe given situations. Given a table and/or graph of a function, you w ill write a function rule that describes that function. What’s my rule? Ask different students to give you numbers between 1 & 50, and tell them the output. Then they must guess the rule. ...

COMPLETING THE SQUARE
... METHOD #2: COMPLETING THE SQUARE f ( x) = x 2 + 2 x - 8 f (x) = x 2 + 2 x + 1 - 8 - 1 f (x) = (x + 1 ) 2 - 9 The function is now in the form of f(x) = a ( x – h ) 2 + k, where ( h, k ) is the vertex and x = h is the axis of symmetry. Therefore, the axis of symmetry is x = - 1. The vertex is ( - 1, - ...

MATH 2113 - Assignment 4 Solutions
... Since this implies that x1 = x2 we have proven f is one-to-one. f (x) is not onto. If we consider the element ’1’ of the co-domain we find that if f (x) = 1 then x + 1 = x − 1 which leads to 2=0 giving a contradiction. Therefore, there is no element of the domain for which f (x) = 1. We conclude tha ...
