Question

Jika f(x) = ax+b maka nilai perubahan fungsi f(x)-f(x+1)=...
a.0
b.1
c.a
d.-a
Caranyaa..

Answer 1

Dik: f(x) = ax + b
Dit: f(x) - f(x + 1) = ..

f(x) = ax + b
f(x + 1) = a(x + 1) + b = ax + a + b

f(x) - f(x + 1) = ax + b - (ax + a + b)
= ax + b - ax - a - b
= -a

jadi jawabannya adalah D. -a

Answer 2

F(x) = ax+b
f(x+1) = a(x+1) + b
= ax + a + b
f(x) -f(x+1) = (ax+b) - (ax+a+b)
= -a

Semoga membantu
