Algebra I

Function Notation
Interval Notation - [a, b]
Average Rate of Change: $\displaystyle \displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

Step 1: Define

g(x) = 4x

Interval [1, 5]

Step 2: Find Change

Substitute in function and points [Average Rate of Change]: $\displaystyle \displaystyle \frac{4(5) - 4(1)}{5 - 1}$
[Fraction] Multiply: $\displaystyle \displaystyle \frac{20 - 4}{5 - 1}$
[Fraction] Subtract: $\displaystyle \displaystyle \frac{16}{4}$
[Fraction] Divide: $\displaystyle 4$

What is the expression for f(x) when we rewrite (5⁻⁴ˣ⁺⁷)÷(125x) as 5^f(x)

alexandr402 [8]

Answer: The answer is f(x) = -7x + 7.

Step-by-step explanation: We are give a relation as follows :

$5^{-4x+7}\div 125^x=5^{f(x)}.$

From here, we need to find the expression for f(x).

Here, we will be using the following properties of exponents :

$(i)~\dfrac{a^x}{a^y}=a^{x-y}.\\\\(ii)~a^x=a^y~\Rightarrow x=y.$

We have

$5^{-4x+7}\div 125^x=5^{f(x)}\\\\\Rightarrow5^{-4x+7}\div 5^{3x}=5^{f(x)}\\\\\\\Rightarrow \dfrac{5^{-4x+7}}{5^{3x}}=5^{f(x)}\\\\\\\Rightarrow 5^{-4x+7-3x}=5^{f(x)}}\\\\\Rightarrow 5^{-7x+7}=5^{f(x)}\\\\\Rightarrow -7x+7=f(x).$

Thus, the required expression is f(x) = -7x + 7.
