Answer:

The function is

g(x) = 5^(-x)

This question can be easily solved by using a graphing calculator

and plotting the graph of g(x)

In the image below, we can see that for each value of x , there is a corresponding value for g(x)

This means that the function does not have any discontinuities. Therefore,

The domain of g(x) is all real numbers  (x ∈ R)

The range is related to the values that can be achieved by g(x),

Since it is a positive exponential function, all values will be g(x)>0

And the range would be (0,∞)

What is an equation for a sine curve with amplitude 2
Naya [18.7K]

ANSWER

y = 2 \:  \sin(x)

EXPLANATION

A basic sine curve has equation in the form:

y = a \:  \sin(x)

Where 'a' is the amplitude.

In this case a=2 because the amplitude is 2.

y = 2 \:  \sin(x)

For a transformed sine function, the general equation is:

y = a \:  \sin(bx + c)  + d

where a=2 is still the amplitude

y = 2 \:  \sin(3x + \pi)

This is also a sine function with an amplitude of 2.

Others include:

y = 2 \:  \sin(x + 1)

y = 2 \:  \sin(4x - \pi)
