Which graph models the function f(x) = −2(3)x? exponential function going through point 0, negative 2 and ending down on the right exponential function going through point 0, 2 and ending down on the right exponential function going through point 0, 2 and ending up on the right exponential function going through point 0, negative 2 and ending up on the right

exponential function going through point 0, negative 2 and ending down on the right

Step-by-step explanation:

y = -2(3^x)

At x = 0, -2(3⁰) = -2

At x = 1, -2(3¹) = -6

Down, when towards right

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
