Provide an misspend vindication.
1) Use the graph to confront the slope-intercept arclass of the equation of the continuity.
Slope______________
1)
x-intercept_________
y-intercept____________
Equation of the continuity_________________
Find the administration esteem.
x2 + 7
; f(4)
2) f(x) =
x3 + 6x
2)
Solve the drift.
3) Using a phone card to establish a hanker removal horizontalter absorbs a horizontal fee of $0.85 plus $0.19 per
exact starting delay the primeval exact. Confront the completion absorb of a phone horizontalter which lasts 8
minutes.

3)
Determine whether the graph is the graph of a administration.
4)
4)
Provide an misspend vindication.
5) Write the equation of a continuity that passes through (3, 9) and (0, -7). Write the definite defense in
the arclass Ax + By = C where A, B, and C are integers delay no spiritless divisors (other than
±1) and A > 0.
Find the vertex of the quadratic administration. Then confront each of the aftercited:
(A) Intercepts
(B) Vertex
(C) Maximum or minimum
(D) Range
6) f(x) = x2 + 4x - 5

5)
6)
Use transformations of the graphs of y = x 2 or y = |x| to delineate a graph of f by influence.
7) f(x) = x - 9 - 4
8) f(x) = 5(x + 3)2 - 2
7)
8)
Give the inclosure and class of the administration.
9) f(x) = x2 + 4

Provide an misspend vindication.
10) The aftercited graph represents the outcome of directing a continuity of transformations to the
graph of a basic administration. Identify the basic administration and recount the transformation(s).
Write the equation for the consecrated graph.
11) Confront the flag arclass of the equation of the continuity dying through the two points.
(2, - 6) and (- 9, 6)
Solve the continuityar equation.
12) 5y - 6 + y = 39 + 2y - 5y

Answer Key
Testname: MATH106 CH 1 WORKSHEET
1) y = -x + 3
23
2)
88
3) $2.37
4) not a administration
5) 16x - 3y = 21
6) Flag arrange: f(x) = (x + 2)2 - 9
(A) x-intercepts: - 5, 1; y-intercept: -5
(B) Vertex (-2, -9)
(C) Minimum: -9
(D) y -9
7)
8)
9) Domain: all genuine numbers; Range: [4, )
10) Basic administration is f(x) = x ; meditate aggravate the x -axis, alter left 4 units, alter down 2 units. f(x) = - x + 4 -2
11) 12x + 11y = - 42
12) {5}
