That means when x=0
e^-0.2x =e^0=1
So f(0)=15/5=3

Answer:

y-intercept of the graph of f(x) is, 3

Step-by-step explanation:

y-intercept states that the graph cross the y-axis.

i.e, substitute x = 0 and solve for y.

As per the statement:

Given the function:

f(x) = y = \frac{15}{1+4e^{-0.2x}}

To find y-intercept:

By definition:

Substitute x = 0 we have;

y = \frac{15}{1+4e^{-0.2 \cdot 0}} = \frac{15}{1+4 \cdot 1}  =\frac{15}{5} = 3

therefore, the y-intercept of the graph of f(x) is, 3

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 5x + 7

g(x) = 3x - 1

<u>Step 2: Find</u>

  1. Substitute in functions:                                                                                    f(g(x)) = 5(3x - 1) + 7
  2. [Distributive Property] Distribute 5:                                                                 f(g(x)) = 15x - 5 + 7
  3. [Addition] Combine like terms:                                                                        f(g(x)) = 15x + 2
