Graph x2 + 9y2 = 25. What are the domain and range? Someone please help me ! (Picture below)

1 answer:

4 0

The equation is equivalent to x2/25 + y2/(25/9)= 1, it is an ellipse equation
the center is C(0,0)
a=5; b= 5/3, so a>b it is a horizontal major axis type (the x-axis)
all that you do is to find all characteristics by following all required formula

Umnica [9.8K]

Answer:

Answer: 4x² - 9x + 20 

Step-by-step explanation:

• General quadratic equation:

${ \rm{ {x}^{2} - (sum \: of \: roots)x + (product \: of \: roots) }}$

• sum of roots → 4 + 5 = 9

• product of roots → 4 × 5 = 20

• substitute:

${ \boxed{ \rm{4 {x}^{2} - 9x + 20 }}}$
