If f(x)=4x+5 and the domain of f is (2,6,10) what is the range of f(x)?

To find the range, you could simply substitute the given values for domain as inputs for x into the function.

For x = 2:

f(2) = 4x + 5

f(2) = 4(2) + 5

f(2) = 8 + 5
f(2) = 13

For x = 6:

f(6) = 4x + 5

f(6) = 4(6) + 5

f(6) = 24 + 5

f(6) = 29


For x = 10:

f(10) = 4x + 5

f(10) = 4(10) + 5

f(10) = 40 + 5

f(10) = 45


Therefore, the range of the function, f(x) = 4x + 5 given the domain of {02, 6, 10} is:

Range: {13, 29, 45}.
