salah satu titik potong kurva y=x²+3x-7 dengan garis y=x+1 adalah..

Intersection Point on Two Graphs.

x² + 3x - 7 = x + 1
x² + 3x - 7 - x - 1 = 0
x² + 2x - 8 = 0
(x - 2)(x + 4) = 0
x = 2 or x = -4

For x = 2, y = 2 + 1 = 3
For x = -4, y = -4 + 1 = -3
The intersection points is (2, 3) and (-4, -3).
