Determine the intercepts of the line. yy y y -intercept: (\Big( ( left parenthesis ,, , comma )\Big) ) right parenthesis xx x x
BlackZzzverrR [31]

Question:

Give all the x and y intercept of the function

f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30}

Answer:

The x intercepts are x = 5 and x = -4

The y intercept is at y = -2

Step-by-step explanation:

Factorizing the numerator of the expression we find the x intercepts as follows;

f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30} =\frac{3(x-5)(x+4)}{2x^3 + 2x^2-34x+30}

Therefore, the x intercept are

x = 5 and x = -4

To find the y intercept, we put x = 0 to get y = -2

Therefore, the y intercept is at y = -2

Factorizing the denominator we find the values for which the equation is undefined

2·x³ + 2·x² - 34·x + 30 = 2·(x-1)·(x-3)·(x+5) which gives

x = 1, 3 and -5.

Ben is going bowing this weekend. It will cost $5 for the shoe rental plus $6 per game bowled. Which equation models the cost, c
elena-14-01-66 [18.8K]

Answer:

C(g) = 5 + 6g

Step-by-step explanation:

Let

C be the cost function for Ben

and  

g be the number of games

As the shoe rental is paid for all the games, it will be added only once. The variable on which the cost will be dependent is g. The number of games will directly affect the cost function. Here g is independent variable.

So, mathematically writing,

C(g) = 5 + 6g
