Find the Y-intercept and x-intercept of the line: 4x- 6y=21

zimovet [89]

Answer:

Step-by-step explanation:

4x-6y=21

divide by 21

$\frac{4x}{21} -\frac{6y}{21} =1\\or~\frac{x}{\frac{21}{4} } +\frac{y}{-\frac{7}{2} } =1\\x~intercept =\frac{21}{4} =5.25 \\y~intercept=-\frac{7}{2} =-3.5$

find the formula for a rational function that satisfies all of the following. its x-intercept is (-3,0). it has a vertical asymp

Norma-Jean [14]

Let that be

$\\ \rm\Rightarrow y=\dfrac{a(f(x))}{g(x)}$

Two vertical asymptotes at -1 and 0

$\\ \rm\Rightarrow y=\dfrac{a(f(x)}{x(x+1)}$

If we simply

$\\ \rm\Rightarrow y=\dfrac{a(f(x)}{x^2+1}$

Denominator has degree 2
Numerator should have degree as 2 and coefficient as 3 inorder to get horizontal asymptote y=3 means the quadratic equation should contain 3x²
But there should be a x intercept at -3 so one zeros should be -3

Find a equation

3x²+9x

Find zeros

3x²+9x=0
3x(x+3)=0
x=0,-3

Horizontal asymptote

3x²/x²
3

So our equation is

$\\ \rm\Rightarrow y=\dfrac{3x^2+9x}{x(x+1)}$
