For what value of c is the function one-to-one?
{(1,2).(2,3), (3,5),(4,7).(5,11).(6,c)}

it is not that hard all u have to do is plot the graph

step-by-step explanation:

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

did u ever get the answers? i need
