Answer:

15, 6 and - 3

Step-by-step explanation:

Given x - y = 3 , then

(a)

5(x - y) = 5(3) = 15

(b)

2x - 2y ← factor out 2 from each term

= 2(x - y) = 2(3) = 6

(c)

y - x ← factor out - 1 from each term

= - 1(x - y) = - 1(3) = - 3

Write an explicit function for f(x) <br> Can anyone help me with this please I’ll mark as brainliest
stiv31 [10]

Answer:

Explicit Function:

Any function which when expressed in terms of the independent variable is called an explicit function. For example, if we write y=f(x)

, then the dependent variable y is given in terms of the independent variable x by the function f(x). Thus y=f(x) is an explicit function. But, g(x,y)=c

is not explicit as it is a combination of both x and y. Such a function is called implicit.

Step-by-step explanation:

What is meant by implicit function?

An implicit function is a function that is defined by an implicit equation. That means the equation contains several variables, including dependent and independent. In other words, it is an equation that relates one of the variables, recognized as the value of the function, with the others regarded as the arguments.

What is an explicit function?

An explicit function is a function that is represented in terms of an independent variable. For example, y = 4x – 7 is explicit where y is a dependent variable and is dependent on the independent variable x.

How do you know if a function is implicit?

If a function is written in the form f(x, y) = 0, we can say that the given function is implicit.

What is implicit function differentiation?

We differentiate or find the derivative for both sides of the equation in implicit function differentiation.

What is explicit and implicit?

In general, “explicit” means clearly stated, whereas “implicit” refers to proposed and not stated directly.

Q1: How are rational exponents and radicals related? Q2: How can the average rate of change be identified for a function? Q3: Ho
masha68 [24]

Answer:

The answer is given below

Step-by-step explanation:

Q1: How are rational exponents and radicals related?

Rational exponents are exponents in fraction form. Radicals are roots (square root, cube root and so on).

The denominator of the rational exponent is the root which is the same as the radical.

Q2: How can the average rate of change be identified for a function?

The average rate of change is ratio of the change in output to the change in input values. The average rate of change for a function is the slope of the function.

It can be gotten by finding the first derivative of he function.

Q3: How do linear and exponential functions compare as the domain increases?

For linear functions as x increases, y also increases by the same amount (i.e rate of change is constant). For exponential function the rate of change increases by a factor known as the multiplier.
