Answer:
Step-by-step explanation:
f(x) = 2x - 3
f(-9)= 2(-9) - 3 = -18 - 3 = -21
f(-3) = 2(-3) - 1 = -6 - 1 = -7
f(1)= 2(1) - 3 = 2 - 3 = -1
Answer:
a) The algebraic notation is 4 ( x -3 ) = 4x -3
b) The algebraic notation is 2x +2
Step-by-step explanation:
<u><em>Explanation:-</em></u>
a)
Let 'x' be the number
Given 'x' is a number, subtract three
⇒ x - 3 and multiply '4'
The result of algebraic is 4 ( x -3 ) = 4x -3
b)
<em>Let 'x' be a number and add one</em>
⇒ (x+1) and then double
∴ The algebraic notation is
(x+1 ) (2) = 2x +2
X represents the even integerx + 2 represents the next even integerx + 4 represents the next even integer The product of the next two even integers(x + 2)(x + 4)x2 + 6x + 8 FOIL
