How can you tell if a graph is linear by looking at a graph or equation? How can you tell if a relationship is exponential by looking at a graph or equation?

1. the graph of a linear function is a line. An equation is linear if its graph forms a straight line.

2. If the ratio of dependent values is the same, then the data is modeled by an exponential equation. Determine an exponential function in the form y = a ⋅ b x y=a \cdot b^x y=a⋅bx with the given graph.

Step-by-step explanation:

answer: -2+√x,-2-√x
