Question

Diketahui f(x)= px+q
f(1)=-5
f(-2)=-11
f(t)=3.
maka t adalah...

Answer 1

F(x) = px + q

f(1) = -5
p + q = -5

f(-2) = -11
-2p + q = -11

p + q = -5
-2p + q = -11
___________ -
3p = 6
p = 2

p + q = -5
2 + q = -5
q = -5 - 2
q = -7

jadi persamaan nya : f(x) = 2x - 7
f(t) = 3
2t - 7 = 3
2t = 3 +7
2t = 10
t = 5
