Question

if F(X)=x2+2x-5find f (2),F(-3)​

Answer 1

Step-by-step explanation:

f(x) = x² +2x-5

f(2) = (2)² + 2(2) - 5 = 4+4-5 = 3

f(-3) = (-3)² + 2(-3) - 5 = 9-6+5 = 8

Answer 2

Answer:

f(2),f(x)=3  

f(-3),f(x)=8

Step-by-step explanation:

Given,

i)x=2

f(x)=x^2+2x-5

f(2)=2^2+2*2-5

   =4+4-5

   =8-5

    =3

ii)x=3

f(x)=x^2+2x-5

   =(-3)^2+2*(-3)-5

   =9-6+5

   =14-6

   =8
