Answer:

Step-by-step explanation:

(-1 -4)/(2 - 3) = -5/-1 = 5

y - 4 = 5(x - 3)

y - 4 = 5x - 15

y = 5x - 11

Consider the exponential function f(x) = 3(one-third) Superscript x and its graph.
Anna35 [415]

Answer:

The growth value of the function is One-third ⇒ True (2nd)

The function shows exponential decay ⇒ True (3rd)

The function is a stretch of the function f(x)=(\frac{1}{3})^{x} ⇒

True (4th)

Step-by-step explanation:

* <em>Lets revise the form of the exponential function</em>

- The general form of the exponential function is f(x)=a(b)^{x}

  where "a" is the initial amount and "b" is the growth factor

- If b > 1, then f(x) is exponential growth function

- If 0 < b < 1, then f(x) is exponential decay function

* <em>Lets solve the problem</em>

- The exponential function f(x)=3(\frac{1}{3})^{x}

∴ The initial value is 3

∴ The growth factor is \frac{1}{3}

∵ The growth factor is less than 1

∴ f(x) is exponential decay function

* Lets chose the true statements

# The initial value of the function is One-third ⇒ Not true

   because the initial value is 3

# The growth value of the function is One-third ⇒ True

   because the growth factor is \frac{1}{3}

# The function shows exponential decay ⇒ True

   because the growth factor is less than 1

# The function is a stretch of the function f(x)=(\frac{1}{3})^{x}

   ⇒ True

  because stretched vertically means multiply f(x) by constant greater

  than 1 and 3 is greater than 1

# The function is a shrink of the function f(x)=(3)^{x} ⇒ Not true

   because the growth factor is not 3
