Answer:
Graph D
Explanation:
Graph A is incorrect because that is a graph of a negative exponential function.
Graph B is incorrect because that is a graph of a square root function.
Graph C is incorrect because that is a graph of a positive exponential function.
Graph D is correct because linear functions are always straight lines. Linear functions have the base equation of y = mx + b . Because there is only one "x" value to the first power, the function increases by the same amount between each "x" value.
