Question

Дана функция y=a−1. При каких значениях a значение функции равно 2?

Answer 1

Ответ:

при а=3

Объяснение:

y = a-1,  y = 2    

a = ?

a - 1 = 2

a = 2+1

a = 3

Answer 2

To find the values of 'a' for which the function y = a - 1 is equal to 2, you can set y equal to 2 and then solve for 'a'. The equation will be:

2 = a - 1

Now, add 1 to both sides of the equation to isolate 'a':

a = 2 + 1

a = 3

So, when 'a' is equal to 3, the value of the function y = a - 1 will be 2.
