1.	the equation of a function is y = 2x - 3. Find i) the value y when x = 4 ii) the value of x when y = -5
Answer» Answer: 1. If X is 4, y = 2 * 4 - 3 = 8-3 = 5 2. If y is - 5, then - 5 = 2X - 3 - 5 + 3 = 2x - 2 = 2 x So x = - 2/2 = - 1/1 = - 1

the equation of a function is y = 2x - 3. Find i) the value y when x = 4 ii) the value of x when y = -5

Answer»

Answer:

1. If X is 4, y = 2 * 4 - 3 = 8-3 = 5

2. If y is - 5, then - 5 = 2X - 3

- 5 + 3 = 2x

- 2 = 2 x

So x = - 2/2 = - 1/1 = - 1
