Please solve it with steps

Answer 1

Answer:

f(8) = 33.84 or -3.2

Step-by-step explanation:

f(x) and f(y) could be taken as any value. Answers will always vary depending on the values of x and y used.

So I'' be taking f(x) as f(4) and f(y) as f(2)

f(4)f(2) = f(16+3) + 3f(6) - 3f(2) + 12

f(4)f(2) = 19f + 18f - 6f + 12

f(4)f(2) = 31f+12

8f^2-31f-12 = 0

f = 4.23 and -0.4

f(8) = 4.23x8 or -.4x8    (answers will always vary and .4 is the same as 0.4)

f(8) = 33.84 or -3.2

pls mark me as brainiest and thank me. Thanks. Also, friend me. ;-)
