For the function y=-2+5sin(pi/12)(x- what is the minimum value

-7

Step-by-step explanation:

We are given that   a function

We have to find the minimum value of y.

We know that range of sin x is [-1,1].

Maximum value of y=3

Minimum value of y=-7

Hence, the minimum value of given function =-7

is this part of a question or something

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.
