How are rational functions similar to linear, quadratic, or exponential functions? How are they different? When are these simila
jeyben [28]

Answer:

See explanation below for further details.

Step-by-step explanation:

A rational consist of two real numbers such that:

\frac{a}{b} =c

If c is a polynomial with a certain grade, then, both the numerator and the denominator must be also polynomials and the grade of the numerator must be greater than denominator.

If c is linear function, that is, a first order polynomial, then a must be a (n+1)-th polynomial and b must be a n-th polynomial.

Example:

If a = x^{2} and b = x, then:

c = \frac{x^{2}}{x}

c = x

If c is a quadratic function, that is, a second order polynomial, then a must be a (n+1)-th polynomial and b must be a n-th polynomial.

Example

If a = 3\cdot x^{3} and b = x, then:

c = \frac{3\cdot x^{3}}{x}

c = 3\cdot x^{2}

But if c is an exponential, both the numerator and the denominator must be therefore exponential function and grade of each exponential function must different to the other.

Example

If a = 10^{2x} and b = 3\cdot 10^x, then:

c = \frac{10^{2\cdot x}}{3\cdot 10^{x}}

c = \frac{1}{3}\cdot 10^{2\cdot x -x}

c = \frac{1}{3}\cdot 10^x

Otherwise, c would be equal to a constant function, that is, a polynomial with a grade 0.

If a = 5\cdot e^{x} and b = -3\cdot e^{x}, then:

Example

c = \frac{5\cdot e^{x}}{-3\cdot e^{x}}

c = -\frac{5}{3}

It is worth to add that exponential functions can be a linear combination of single exponential function, similar to polynomials.

Example

5\cdot a^2\cdot x -9

1+4=5 2+5=12 3+6=24 5+8=? What's the answer
Vilka [71]

I have seen this problem before, except it was worded differently. Is this the problem you wished to express?

1+4=5, 2+5=12, 3+6=21, 8+11=?                                                                          

If so, then your answer is to simply add the last answer to the next problem. If not, then I am afraid I cannot help you.

1+4=5

5+2+5=12

12+3+6=21

21+8+11=40

Which function is a shrink of the exponential growth<br> function shown on the graph?.
ale4655 [162]

Step-by-step explanation:

An exponential function is represented by function,

y = a \times  {b}^{x}

Where a is the y intercept and b is the growth factor.

The graph passes through (0,1) which is our y intercept so a=1

Know let find b.

The graph pass through (1,3) so plug in 1 for x and 3 for y.

3 = a  \times 3 {}^{1}

a = 1

So our base function is

y = 1 \times 3 {}^{x}

In order for this function to shrink, we must shift the y intercept such that it is less than 1 but greater than -1.

So the only option is

y =  \frac{1}{2} (3) {}^{x}

Because 1/2<1
