Find f(-2) for the following problems. Problem A: f(x) = x3 + 5
Problem B: f(x) = x2 - 2
Which statement is correct?
a
Problem A > Problem B
b
Problem A < Problem B
Problem A = Problem B
d
Cannot be determined

a. Problem A > Problem B

Step-by-step explanation:

Problem A:

f(x) = x3 + 5

f(-2) = (-2)3 + 5

f(-2) = (-6) + 5

f(-2) = -1

Problem B:

f(x) = x2 - 2

f(-2) = (-2)2 - 2

f(-2) = (-4) - 2

f(-2) = -6

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
