Let f(x)=x+a/x+b such that f(f(1)=0 & f(2)=-3 then a& b resctivily are.

a, 1,-5/3 b, -5/3,3 c, 1,-3 d, none of the above

The value of a = - 1  ,   And b =    

Step-by-step explanation:

Given as :

Function f(x) =

And f(f(1)) = 0     And f(2) = - 3

Now For , x = 2 , y = - 3

I.e  f(2) =

or,  - 3 =

I.e 2 + a = - 6 - 3b

Or, a + 3b = - 8               ....... 1

Again  f(f(1)) = 0

So,   = 0

Or,  1 + a = 0

∴    a = - 1

So , put htis value of a i n eq 1 , we get value of  b

So , - 1 + 3b = - 8

Or,   3b = - 7

∴       b =

Hence The value of a = - 1  ,   And b =    Answer

yes. we do proportions in probabilities.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
