Question

Diketahui f(x)=7x+p dan f(2)=10.Nilai f(3)+f(-2)=....

Answer 1

F(2) = 7.2 + p = 10
f(2) = 14 + p = 10
p = 10-14 = -4
f(3) - f(2)
((7.3) - 4) - 10 = 17 - 10 = 7

Answer 2

JAWAB

f(x)=7x+p
◆ f(2)=10, maka
⇨ 7(2)+p = 10
⇨ 14 + p = 10
⇨ p = 10-14
⇨ p = -4

Jadi f(x) = 7x + p = 7x + (-4) = 7x - 4
maka
f(3) = 7(3) - 4 = 21 - 4 = 17
f(-2) = 7(-2) - 4 = -14 - 4 = -18
maka
Nilai f(3) + f(-2)= 17 + (-18) = 17-18 = -1
