Answer:
1 1/8 or 9/8
Step-by-step explanation:
Set up a proportion. The proportion will be teaspoons of chili powder over pound of vegetables.
The first proportion will be..
x is 3/4 and y is 1/2. Across from that proportion make another one
x is "n" because you're trying to figure out how much chili powder you need. y is 1 3/4.
Multiply 3/4 and 1 3/4, which is 9/16. Then, divide 9/16 and 1/2, which is 9/8. Simplify it to 1 1/8, and Maxwell will need 1 1/8 teaspoons of chili powder.
Hope this wasn't too confusing :)
The domain of a(x) is all of R. The domain of b is the range where 
. We can calculate the composition boa by changing in the expression for b, every x with a(x). Hence, boa(x)=
=
. Again for a function with a root to be defined, we need that the expression under the square root has to be positive. Hence, 3x-3
0.Thus, the set where this holds is 
. This is also the domain of the function boa(x).
