Answer : 2x + 3 (Option D)
When x = 1, 2(1) + 3 = 5
When x = 2, 2(2) + 3 = 7
When x = 3, 2(3) + 3 = 9
When x = 4, 2(4) + 3 = 11
Question 22)
The square of y decreased by the quotient of 28 and 7.
Quotient of 28 and 7 = 28/7
Decreased by square of y = -y²
Therefore the expression is 28/7 - y² (Option A)
