If a(x) = 2x - 4 and b(x) = x + 2, which of the following expressions produces a quadratic function? (ab))
O (a - b)^)
O (a + b)(x)

Step-by-step explanation:

Data provided in the question

a(x) = 2x - 4

b(x) = x + 2

Now we go through each options

First option

Second option

Third option

= x - 6

Fourth option

= 3x - 2

As we can see from the above options only option A is correct i.e it only produced a quadric function
