diketahui fungsi f:x--->(2m+1)x+7.jika f(-1)=-4,maka nilai f(m)sama dengan.....
plis jawab ya
soal no 27,pake cara y makasihh

Answer 1

F(x) --> (2m+1)x+7
F(-1) = -4
-(2m+1) +7 = -4
-2m -1 + 7 = -4
-2m = -10
m = 5

F(m) = F(5)
(2×5 +1)5 + 7 = 62.

Answer 2

F(x)= (2m+1)x+7
= 2mx+1x+7
f(-1)=2mx+1x+7=-4
2m(-1)+1(-1)+7=-4
4=-4
