Use the graph of f(x) to answer the question. What is the output of f when x=−6? Enter your answer as a number, like this: 42

For input value, x = -6, output value will be y = 1.2

Step-by-step explanation:

In this question graph of a quadratic 'f' function has been given.

Input values of a function are represented by the x-values and output values by the y-values on the graph.

Let's take a point (5, -1) on this graph.

For input value of 5, output value of the function is (-1).

Similarly, for an input value of x = -6, output value of the function will be y = 1.2

[ordered pair (-6, 1.2) given on the graph)

it has the same slope and a different y-intercept

hope this : )

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
