Question

ff x is equal to (x^2 - 8) /( x^2 + 2) prove that it is neither one one onto where its function is defined from real number to real number

Answer 1

sorry I don't know but can you please say thanks please

Answer 2

Answer:

Step-by-step explanation:

y=x^2-8 / x^2 + 2

take derivative of function

dy/dx=x^2+2 (2x) - x^2-8 (2x) / (x^2+2)^2

here derivative can take positive as well as negative

so many one
