Answer 6

For the graph to be a function, there should be 1-1 relationship of input with outputs. This is to say that there should be a unique output for every input.
Is such the case?

Answer 9

hold on. plot on x-y graph first. talking to friend on whatsapp.

Answer 10

yes.

Answer 11

a) yes it's a function as different values of y for different x's.

Answer 12

b) f(x=7) = 2*(7) +13 =14+13 = 27 for relation b
for relation a x for x =7 y =8, so the given relation y =2x+13 has greater value.

Answer 13

c) f(x) = 2x +13 = 75
2x = 75-13
2x =62
x=31

Answer 14

for part A))

Answer 20

hm?

Answer 21

A))) tHE FUNCTION IS NOT A.P. IT'S

f(x)=3x-13, yes it's a function. using lines.

B))) f(x=7) = 2*(7) +13 =14+13 = 27 for relation b
for relation a x for x =7 y =8, so the given relation y =2x+13 has greater value.

C))c) f(x) = 2x +13 = 75
2x = 75-13
2x =62
x=31

Sorry! Do the corrections.
