Question

Keshawn is asked to compare and contrast the domain and range for the two functions.

f(x) = 5x
g(x) = 5x

Which statements could he include in his explanation? Select two options.

The domain of both functions is all real numbers.
The domain of f(x) is x > 5.
The domain of g(x) is x > 5.
The range of f(x) is y > 0.
The range of g(x) is y > 0

Answer 1

Select:
- The domain of both functions is all real numbers.
- The range of g(x) is y > 0.

Reason: f(x)=5x is a linear function with domain (−∞, ∞) and range (−∞, ∞). g(x)=5^x is an exponential function with domain (−∞, ∞) and range (0, ∞). The other choices are false.
