I only need help with 5 and 6 Please help me! I’ll give a lot of points! And I need an explanation!♥️

Look at explantation.

Step-by-step explanation:

5. It's the first and last one.

6. It's the third one.

Step-by-step explanation:

5: y=[x+3] FALSE

y=-[x-3] FALSE

y=-[x]-2 FALSE

y= [x+8]+5 FALSE

conclusion: none in 5 are right.

explanation: unable to identify a local extrema l

6: y=1/4[x]+5 FALSE

y=-[x]-2 TRUE

y= -7[x+5] TRUE

y= 3[x-2] FALSE

conclusion 2/4 are correct.

explanation: using desmos i could see that 2 had a. shift to the left and 2 were to the right

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.
