Tìm giá trị của x :
Bây giờ, có hai trường hợp :
Trường hợp 1. khi nào x + 3 = 0
Trường hợp 2. khi nào x - 2 = 0
Tôi hy vọng nó đã giúp !
Tan(3x) = 1
3x = arctan(1) = pi/4, -3pi/4
x = (pi/4)/3 = pi/12 or (-3pi/4)/3 = -pi/4
Therefore, x = pi/12 or -pi/4
A parabola is a curved shape in a graph that has either a maximum or a minimum (which is the fixed point) and any point is equidistant from that fixed point. You can tell it is a parabola because most likely in an equation the x with be squared.
Step-by-step explanation:
-3x + 27= -3
-3x = -3-27
-3x = -30
x= 10
