If f:x = x² - 4 when x is a real number, find f-¹(5)
​

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,

mrb

you just switch the numbers basically so it would be 3/17

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

the answer is: -22 also a

hope i
