Question

f (x)=x^2+2x,find f (3)-f (2)divided by f (1)​

Answer 1

Answer:

f(x) = x²+2x

if x =3 put the value of x in f(x)

f(3) = (3)²+2×3

= 9+6

= 15

now x = 2

put the value of x in f(x)

f(2) = (2)²+2×2

= 4+4

= 8

if x=1 put x= 1

f(1) = (1)²+2×1

= 1+2

= 3

f(3)-f(2)÷f(1)

15-8÷1 = 7÷1 = 1
