Which expression is a difference? a) (6 - 4) x 5 b) 6 - (4 x 5) c) 8 + (5 - 2) d) (6 - 4)(3 - 1)

B

Step-by-step explanation:

A difference is the result of subtraction. While each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. This means subtraction must be outside of the parenthesis. Only B has this.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
