4. for the function defined by: f(x)={x^2 x< =1}
{2x+1 x> 1} part i: evaluate f(0).
a. identify the function that will be used when x = 0.
b. find the value of this function when x= 0. part 2: graph f(x). a. graph the first function completely. b. on the same graph you used to answer part (a), graph the second function completely. c. identify the value of x at which the function changed. remove the parts of each line that are not included in domain of the corresponding function. d. place open and close circles appropriately on the ends of each line to complete the function.

step-by-step explanation:

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.

oof. u are asking for t much

answer by jkismyhusbandbae:

a) how close a measured value is to the actual (true) value.

  measure of length.   there are 12 inches in a foot, and 36 inches in a yard.   one inch is exactly 2.54 centimeters.

accuracy is how close something is to an actual answer but it is not exactly correct.
