Question

If 5 is an element in the domain of f(x) = 7x - 22/4, what is the corresponding element in the range?

a) 0.75
b) 3
c) 8.5
d) 2.75

Answer 1

To find the corresponding element in the range, substitute the given element in the domain into the function f(x) and simplify the expression. In this case, the corresponding element in the range is 29.5.

Step-by-step explanation:

To find the corresponding element in the range, we need to substitute the given element in the domain into the function f(x) and simplify the expression.

For f(x) = 7x - 22/4, if x = 5, we substitute this value into the function:

f(5) = 7(5) - 22/4 = 35 - 5.5 = 29.5

So, the corresponding element in the range is 29.5. Therefore, the correct answer is c) 8.5.
