Question

Дана функция y=−a+1. При каких значениях a значение функции равно 4?

Answer 1

y=−a+1

-a+1=4

-a=4-1

-a=3  /:(-1)

a= - 3

Answer 2

Значение функции это у, подсталяем значение у=4 и находим а:

4=-а+1, а=-4+1=-3

Ответ: а=-3

Answer 3

To find the values of "a" for which the function y = -a + 1 is equal to 4, we need to set y equal to 4 and solve for "a".

Given: y = 4

Substitute y with 4 in the function: 4 = -a + 1

Now, we want to isolate "a" on one side of the equation. To do that, we'll move the constant term (1) to the other side by subtracting it from both sides of the equation:

4 - 1 = -a + 1 - 1

This simplifies to:

3 = -a

Finally, to solve for "a," we'll divide both sides by -1:

a = -3

So, when "a" is equal to -3, the value of the function y will be 4.
