F(x) = x^2+x-2/x^2-3x-4
Andrej [43]

i. Domain and Range

The given function is

f(x)=\frac{x^2+x-2}{x^2-3x-4}


The domain of this function is,

x^2-3x-4\ne 0

(x-4)(x+1)\ne 0

x\ne4,xne -1


The range refers to the y-values for which x is defined. x  is defined for all values of y.

The range is all real numbers. See graph

ii. x-and-y-intercept

For x- intercept intercept we put f(x)=0

This implies that;

\frac{x^2+x-2}{x^2-3x-4}=0


This will give us

x^2+x-2=0

\Rightarrow x^2+x-2=0


\Rightarrow x^2+2x--x-2=0

\Rightarrow x(x+2)-1(x+2)=0

\Rightarrow (x+2)(x-1)=0


\Rightarrow (x+2)=0,(x-1)=0

\Rightarrow x=-2,x=1

The x-intercepts are (-2,0),(1,0)


For y-intercept, we put

x=0 to obtain;

f(0)=\frac{0^2+0-2}{0^2-3(0)-4}

f(0)=\frac{1}{2}

The y-intercept is

(0,\frac{1}{2})

iii. Horizontal asyptote

Since degree of the numerator and the denominator are the same, there is a horizontal asymptote

To find the horizontal asymptote.


We divide the leading coefficient of the numerator by the leading  coefficient of the denominator.


The horizontal asymptote is y=\frac{1}{1}=1

iv. Vertical asymptote

To find the vertical asymptote, we equate the denominator to zero to get;

x^2-3x-4=0


This implies that;

x^2+x-4x-4=0

Split the middle term

x(x+1)-4(x+1)=0

Factor

(x+1)(x-4)=0

Factor further

(x+1)=0,(x-4)=0

x=-1,x=4


The vertical asymptotes are x=-1,x=4

A jar contains 770 beans. Of them, 350 are mung beans and the rest are kidney beans. What is the ratio of mung beans to all the
MatroZZZ [7]

Answer:

5 MB : 16 B

Step-by-step explanation:

First, find the GCF of 770 and 350. ( 70 )

Next, divide both numbers by 70

770 / 70  = 11 Kidney beans

350 / 70 = 5 Mung beans

It says ratio of mung beans to <u>all</u> beans.

11 KB + 5 MB = 16 B

5 Mung beans to 16 Beans
