He is false the equation should be as follows
Plug in the given values and you'll see its option 2.
x=0 , f(x) = 0^2 + 1 = 1
x = 1 , f(x) = 1^2 + 1 = 2
x = 2, f(x) = 2^2 + 1 = 5
Answer:
772.2
Step-by-step explanation:
Using the method of cross- product
•
=
⇒ ad = bc, thus
85.8 × 9 = 11 × 70.2 = 772.2
1, 2 and 6 are right.
Solution go on infinitely
all solution are negative because its number less than -20
solution contain rational among others
