Which of these tables could represents quadratic function? x. y -2. -8 -1. -5 0. -2 1. 1 2. 4 x. y -2. 8 0. 2 2. 0 4. 2 6. 8 x. y 1. -1 2. 4 0. -4 -1. -7 -2. -10 x. y 1. 1 2. 4 0. 4 -1. -7 -2 -10

When values of a quadratic function are listed in a table with x-values having a constant difference, the y-vlaues will have a constant (non-zero) second-difference.

Here, we can list first and second differences for the values in the given tables to identify the quadratic function.

Table 1.

Table 2.

Table 3.

Table 4.

___

The appropriate choice is Table 2.

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
