Question

Дана функция y=2x+12 с облостью определения D=R. При каких значениях x значение фукциии y равно 38?

Answer 1

Подставляем в функцию y(x) в роли ординаты искомых точек наше значение 38:

$38=2x+12$
$38-12=2x$
$26=2x$
$13=x$
$x=13$

Ответ: 13

Answer 2

Finding the Value of x for y=38 in the Function y=2x+12

To find the values of x for which the function y=2x+12 equals 38, we can set up the equation:

2x + 12 = 38

Now, let's solve for x:

2x = 38 - 12 2x = 26 x = 26 / 2 x = 13

So, the value of x for which the function y=2x+12 equals 38 is x = 13.

This information is based on the mathematical equation y=2x+12 and the process of solving for x to make y equal to 38
