Evaluate the Function f(-1)=8/(1+3e^(-0.7x))

$f (- 1) = \frac{8}{1 + 3 e^{- 0.7 x}}$

Step 1

Replace the variable $x$ with $- 1$ in the expression.

$f (- 1) = \frac{8}{1 + 3 e^{- 0.7 \cdot - 1}}$

Step 2

Simplify the result.

Multiply $- 0.7$ by $- 1$ .

$f (- 1) = \frac{8}{1 + 3 e^{0.7}}$

The final answer is $\frac{8}{1 + 3 e^{0.7}}$ .

$\frac{8}{1 + 3 e^{0.7}}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$\frac{8}{1 + 3 e^{0.7}}$

Decimal Form:

$1.13616059 \dots$
