1. 2 3/4 + 1 1/4

This problem is a simple addition problem, all you have to do is add 2+1 (3) and then if the denominator of the fractions are the same, then you add freely without changing the denominator. So we add 3/4+1/4 (4/4) If the numerator is equivalent or greater than the denominator; we "Convert". So, since the numerator is equal to the denominator; we will Convert that fraction into a whole number (1) because a fraction is nothing but a part. If all the parts of the fraction are put together, then we will get a whole. After that we add the 1 to the 3 (4). The answer to this problem is 3.

2. 2 3/4 + 2 3/4

This problem is relatively easy. Do the steps above, but you will see that the fraction has turned into a improper fraction (6/4) Now, if you've already subtracted 4 from the numerator, then you've done a great job! Now we add 1 to the whole numbers, making it 5, but we still have work to do. There are still 2 parts left to the fraction, which means we have to make a mixed number. All you do is take the 5 and put 2 over 4, we can reduce the fraction, so let's go ahead and do so. The answer to this problem would be 5 1/2.

H(x) = 1/3x - 1 if h (15)
dalvyx [7]

Answer:

(

h

∘

f

∘

g

)

(

x

)

is known as a composite function. Here's how composite functions work:

let's say that  

x

=

1

. Your function  

g

(

x

)

=

1

3

(

x

)

now produces a  

y

output of  

1

3

, since  

g

(

1

)

=

1

3

(

1

)

. Within a composite function, the y-value of one function becomes the x-value of the next, like so:

g

(

1

)

=

1

3

⇒

f

(

1

3

)

=

17

3

⇒

h

(

17

3

)

=

17

Therefore,

(

h

∘

f

∘

g

)

(

1

)

=

17

Based on this, to find the function for  

(

h

∘

f

∘

g

)

(

x

)

(combined from right to left, by the way), simply replace  

x

in  

f

(

x

)

with the function  

g

(

x

)

, and replace  

x

in  

h

(

x

)

with the function of  

(

f

∘

g

)

(

x

)

, to get  

(

h

∘

f

∘

g

)

(

x

)

.

This, simplified, is equal to  

2

x

+

15

, and therefore  

(

h

∘

f

∘

g

)

(

1

)

=

2

(

1

)

+

15

=

17

Hope that helps!
