Question

Let A={1,2,0,-1} B={1,3,-1,-3} and function f:
AB,
f(x) = px +q. If f={(1, 1,), (2, 3), (0, -1), (-1, -3)}then find value of p and q.​

Answer 1

Answer:

p= 2, q = -1

Step-by-step explanation:

px+q = t(xl

when x =1, f(x) = 1 hence p + q = 1

when x= 0, f(x) = -1 hence q = -1

from above, on solving the two equations we get

p=2, q= -1
