PLZ HELP ME (I need step by step workout and answer)

Mathematics
1 answer:
FrozenT [24]3 years ago

Answer:

f⁻¹(x) = 5th root(x/4 - 5/4)

Step-by-step explanation:

f(x) = 4x^5 + 5

substitute y for f(x):

y = 4x^5 + 5

swap x and y:

x = 4y^5 + 5

subtract 5 from each side:

x - 5 = 4y^5

divide both sides by 4:

(x - 5)/4 = y^5

get the 5th root of each side:

y = 5th root(x/4 - 5/4)

f⁻¹(x) = 5th root(x/4 - 5/4)
