Question

6.12 При каком значении переменной функция y=9-x\15+2x не определена ?

Answer 1

Функция не определена, если знаменатель =0
15+2x=0
x=-7,5
при х=-7,5 функция не определена

Answer 2

To find the value of the variable for which the function y = 9 - x/15 + 2x is undefined, we need to identify the values that would result in division by zero. The function is undefined when the denominator becomes zero, as division by zero is not defined in mathematics.

The denominator in this function is (15 + 2x), so we need to solve the equation:

15 + 2x = 0

Subtract 15 from both sides:

2x = -15

Now, divide both sides by 2:

x = -15 / 2

So, when the variable x is equal to -15/2, the function y = 9 - x/15 + 2x is undefined.
