Which ordered pair does not lie on the graph of h(x)=-2x + 7

a (-2, 3)
, 9)
c (3, 1)
d (4, -1)

A (-2, 3)

Step-by-step explanation:

1. To know which oredered pairs does not lie on the graph, you must substitute the x-coordinate of each one of thm into the function and if you obtain the y-coordinate shown in that ordered pair, then that point lies on the graph.

2. Therefore, you have:

A. x=-2

(It does not lie on the graph).

B. x=--1

(It lies on the graph).

C. x=3

(It lies on the graph).

D. x=4

(It lies on the graph).

Therefore, the answer is the option A.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

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
