Which of the following functions models exponential decay a:f(x)=12 times 3^x b:y=2 times 0.8^x c: y=-3x^2 d:f(x)=1.8^x

you need to show the graph

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

b. 2 and 4
