Question

range of f(x) = 20^x

Answer 1

Answer:

Step-by-step explanation:

f(X) = 20^x

f*X = 20*X

FX = 20x

Answer 2

The range for f(x) = $20^{x}$ is (0, ∞)

Given: f(x) = $20^{x}$

To find: range of f(x)

Solution:

The range of a function is the extent of values of the output of a function.

Given function is f(x) = $20^{x}$

Let y = f(x)

We know that

If y = aˣ and a>0, then y∈ (0, ∞)

Now, y = 20ˣ and 20>0

⇒ y ∈ (0, ∞)

⇒ f(x) = (0, ∞)

⇒ Range of f(x) = 20ˣ is (0, ∞)
