A quick way to estimate the sum of two numbers is to round each number and then add the rounded numbers
case a) We round the number to the nearest hundred
so
Round up is equal to
Round up is equal to
Find the estimate sum
case b) We round the number to the nearest tens
so
Round up is equal to
Round down is equal to
Find the estimate sum

The value of h{g[f(x)]} is 7 after finding the composite function option (a) 7 is correct.
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
f(x) = x²
g(x) = x + 6
h(x) = 7
g[f(x)] = x² + 6
h{g[f(x)]} = 7
Thus, the value of h{g[f(x)]} is 7 after finding the composite function option (a) 7 is correct.

Answer:
a. 7
Step-by-step explanation:
f(x) = x²
g(x) = x + 6
h(x) = 7
g[f(x)] = x² + 6
h{g[f(x)]} = 7
