diketahui f(x)=2x+n dan f(2)=1.Nilai dari f(7)-f(4) adalah...

f(x) = 2x + n

f(2) = 1
2(2) + n = 1
n = 1 - 4
n = -3

jadi f(x) = 2x - 3

f(7) - f(4)
= 2(7) - 3 - 2(4) + 3
= 14 - 3 - 8 + 3
= 6

f(x) = 2x + n
f(2) = 1
(2x2) + n = 1
4+n=1
n=1-4
n = -3

Maka, f(x) = 2x - 3

f(7) - f(4)
= ((2x7) + 3) - ((2x4) + 3)
=( 14 + 3) - (8+3)
= 17-11
= 6

Jadikan yang terbaik yaaaaw
