you mean question 19

Answer 2

Yes and #20. But are 17 and 18 right?

Answer 3

question 17 is right but 18, whicha has the same concept as 19, is not right.

Answer 4

for both questions 18 and 19, just solve it like this

f(x)=2(x+10)

and f(x)= 24 then just substitute

f(x)=2(x+10)
24 = 2x + 20

and then just solve for x

Answer 6

Q 20

(3,4) , (0, 1), (3,2), ( 4,5)
is a relation but not a function
because 3 in the domain maps to 4 and 2
which makes it a one-to-many relation which is not a function.

Answer 7

functions are either one-to-one or many-to-one

Answer 8

BY THE way just apply the same concept to question 19 be cuase they are basically the same question with different numbers
