How do you find the rate of change of a function?

Kobotan [32]

Answer:

We calculate the slop of a line.

How to find the slope:

Pick any two points on a graph

The formula of slope is $\frac{Y2-Y1}{X2-X1}$

For example we have two points that contains the coordinates (5,2) (7,4)

Inserting them to the formula would result in:

$\frac{4-2}{7-5}$

= $\frac{2}{2}$

Our rate of change is rise 2, run 2.

High expression is equivalent to ^4 square root x^10

Talja [164]

In order to find which expression is equivalent to $\sqrt[4]{x^{10}},$ simplify all given expressions:

$\sqrt[4]{x^{10}}=x^{\frac{10}{4}}=x^{\frac{5}{2}}=x^{2.5}.$

$x^2(\sqrt[4]{x^2})=x^2\cdot x^{\frac{2}{4}}=x^2\cdot x^{\frac{1}{2}}=x^2\cdot x^{0.5}=x^{2.5}.$

$x^{2.2}.$

$x^3(\sqrt[4]{x} )=x^3\cdot x^{\frac{1}{4}}=x^3\cdot x^{0.25}=x^{3.25}.$

$x^5.$

Therefore,

Answer: correct choice is A
