Question

a certain linear function f(x) is such that f(0)=4, f(2)=p, and f(-1)=q. what is the value of p+2q?

Answer 1

zero

Answer 2

how did you get zero?

Answer 3

is it ryt or not

Answer 4

say
f(x) = px+qx +4

Answer 5

f(2)+2f(-1)

Answer 6

it satisfies f(0) = 4

Answer 7

how do you get this?

Answer 8

il tell you that in the end :)
first can we take the function as
f(x) = px+qx +4

and see if we can figure out what p+2q is ?

Answer 9

how do you figure that out?
