Question

Can someone help please I need help

Answer 1

C= 25n+100

Explanation:

Let's see what's in the graph :

• the image of 4 is 200 C(4)=200
• C(2)= 150

let m be the slope of this function :

• m=
  `(200-150)/(4-2)`=25

The first value in the graph is 100 wich is c(0)=100

• so the equation is : c=25n+100
