graphing functions equation

In plotting the graph of any trigonometric function the angle may be regarded as measured either in radians or in degrees. If a trigonometric function is combined with an algebraic function it is customary to assume that the angle is measure in radians...

A graph is a function if any vertical line intersects the graph at ____. => only one point or not more than two points or two points or more than two points..

A graph is a function if any vertical line intersects the graph at ____. => not more than two points or more than two points or two points or only one point..

From the graph it is clear that the curve repeats itself every 360 o (2 p rad). This fact is expressed by the statement that the function has a period of 360 o (2 p radians). In symbols we write cos(x + 360 o .n) = cos(x + 2 p n) = cos x where n is a positive or negative i..

Graph the quadratic function y = - ( 1 4 ) x 2 . Indicate whether the parabola opens up or down. Determine the equation of the axis of symmetry and the coordinates of the vertex. Also mention if the vertex is a maximum or a minimum point. => Graph B; opens do..

Which of the following is the graph of a relation, that has an inverse, which is a function? => Graph B or Graph C or Graph A or None of these..

Which of the following graphs represents an identity function? => Graph A or Graph B or Graph C or all the three..

Identify the graph that represents a linear function. => Graph 3 or Graph 1 or Graph 4 or Graph 2..

Identify the graph that represents a linear function. => Graph 2 or Graph 1 or Graph 3 or Graph 4..

Choose the graph which is not a function? => Grpah 1 or Graph 2..
