What is f[g(4)] for the following functions?

f(x) = 2x2− 5

g(x) = 3x − 7

f[g(4)] = 74
f[g(4)] = 45
f[g(4)] = 27
f[g(4)] = 5

36 is the final answer! : )

step-by-step explanation:

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.
