PERSAMAAN GARİS SİNGGUNG KURVA
persamaan K : 18x – 6y + 3 = 0
a = 18
b = – 6
c = 3
m = –18
–6
m = 3
f(x) = x² – 7x + 12
f'(x) = m
2x – 7 = 3
2x = 7 + 3
2x = 10
x = 10
2
x = 5 → x1 = 5
f(x) = y
f(5) = 5² – 7×5 + 12
y = 25 – 35 + 12
y = –10 + 12
y = 2 → y1 = 2
Persamaan garis singgung kurva :
y – y1 = m(x – x1)
y – 2 = 3(x – 5)
y – 2 = 3x – 15
y – 2 – 3x + 15 = 0
