Question

Y= 2x-1 Найти у(-3) и y(3)​

Answer 1

1)y(3)           2)y(-3)​

3=2x-1         -3=2x-1

2x=4            -2=2x

x=2               x=-1

Answer 2

To find the values of Y when X is equal to -3 and 3, we can substitute the given values of X into the equation Y = 2X - 1. Let's calculate:

1. For X = -3: Y = 2(-3) - 1 Y = -6 - 1 Y = -7

So, Y(-3) = -7.

2. For X = 3: Y = 2(3) - 1 Y = 6 - 1 Y = 5

So, Y(3) = 5.
