Which is a stretch of an exponential decay function?
Marta_Voda [28]

Answer:

The correct option is C. The function f(x)=\frac{5}{4}(\frac{4}{5})^x is a stretch of an exponential decay function.

Step-by-step explanation:

The general form of an exponential function is

f(x)=ab^x

where, a is the initial value and b is the growth factor.

If b<1, then it represents a decay function and if b>1, then it represents a growth function.

Let k be a stretch and compression factor.

g(x)=kf(x)

If k<1, then it represents vertical compression and if k>1, then it represents vertical stretch.

In third function

f(x)=\frac{5}{4}(\frac{4}{5})^x

k > 1

b < 1

Therefore the function f(x)=\frac{5}{4}(\frac{4}{5})^x is a stretch of an exponential decay function.

never [62]

Answer:

A

Step-by-step explanation:

Since F(x) is opening downwards the x component must be multiplied by a - number. The number in the parentheses represents horizontal movement, but it must be remember that if negative it moves right and if positive it moves left. The number outside the parentheses represents represents vertical movement and is more intuitive, where positive is up and negative is down. Keeping this in mind it should be A
