Find the intercepts of function f(x) = -x³ / x²+9 ​

Mathematics
1 answer:
Brrunno [24]3 years ago
7 0

Answer:

x-intercept (0,0)

y-intercept (0,0)

Step-by-step explanation:

The given function is

f(x) =  \frac{ -  {x}^{3} }{ {x}^{2}  + 9}

To find the x-intercept, we substitute y=f(x)=0

This implies that:

\frac{ -  {x}^{3} }{ {x}^{2} + 9 }  = 0

-  {x}^{3}  = 0 \cdot( {x}^{2}  + 9)

- {x}^{3}  = 0

{x}^{3}  = 0

x = 0

Therefore the x-intercept is (0,0)

To find the y-intercept we substitute x=0

f(0) =  \frac{ -  {0}^{3} }{ {0}^{2} + 9 }

f(0) =   \frac{0}{9}  = 0

The y-intercept is (0,0)

The equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x

<h3>How to determine the equation?</h3>

The attached table of values represents the missing piece in the question.

Start by calculating the rate of change using:

m = (y2 - y1)/(x2 - x1)

This gives

m = (14.77 - 10.55)/(7- 5)

Evaluate

m = 2.11

The equation is then calculated using:

y = m(x - x1) + y1

This gives

y = 2.11(x - 5) + 10.55

Evaluate

y = 2.11x - 10.55 + 10.55

y = 2.11x

Hence, the equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x
