Question

Suatu fungsi f:x → 2x+7. Bila f (-1) = m, maka nilai F(m)=....
tolong pake caranya

Answer 1

Verified answer

F(x) = 2x + 7

f(-1) = m
f(-1) = 2(-1) + 7
f(-1) = -2 + 7 = 5
m = 5

f(m) = 2(m) + 7
m = 5
f(5) = 10 + 7 = 17

Answer 2

Verified answer

F(x) = 2x + 7

f(-1) = 2(-1) + 7
<=> m = -2 + 7
<=> m = 5

f(m) = 2m + 7
f(m) = 2(5) + 7
f(m) = 10 + 7
f(m) = 17
