Step-by-step explanation:
so you put the value of F into x and make an equation
Answer:
Step-by-step explanation:
f(x) = px + q
f(-2) = 4
p*(-2) + q = 4
-2p + q = 4 -----------------(I)
f(3) = 4
p*3 + q = 4
3p + q = 4 ---------------------(II)
Subtract equation (II) from (I)
(I) -2p + q = 4
(II) 3p + q = 4 {Subtract}
- - -
-5p + 0 = 0
-5p = 0
p = 0
Plugin p = 0 in equation (I)
0 + q = 4
q = 4
p = 0
q = 4
