Diberikan rumus fungsi
f(x) = 2x - 3

f(m) = -7
2(m) - 3 = -7
2m - 3 = -7
2m = -7+3
2m = -4
m = -4/2
m = -2

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

Maka,
nilai dari m+n = -2-1 = -3

semoga membantu

f(x) = 2x - 3

* f(m) = -7
f(x) = 2x - 3
f(m) = 2.m - 3 = -7
f(m) = 2m - 3 = -7
2m = -7 + 3
2m = -4
m = -2

* f(1) = n
f(1) = 2.1 - 3
= -1 , maka n = -1

Maka m+n adalah -2+(-1)=-3
