y = 8 - 2*x
Which means 0 = -1!
0 since anything to the power of 0 = 1
1
100 = 1.Any number to the power of 0 equals 1.
Slope, m, equals (y2-y1)/(x2-x1). Slope is (0-(-1))/(0-(-1)) or 1/1 or 1.
The unit step function at t=0 is defined to have a value of 1.
2
0 because y=1 can be written as y = (0)x +1 and its gradient is 0.
-1/3,1/3and 5/3
y = 2, 4, 6, 8
y = x2 + x = 0 x (X + 1) = 0 x = 0 is one solution x = -1 is the other
4x2-5x+1 = 0 (4x-1)(x-1) = 0 x = 1/4 or x = 1
Just like the sine function displaced by pi/2. In other words the cosine equals 1 at 0 degrees, 0 at 90 degrees, -1 at 180 and so on.
If a > 0, it is stretched, in the vertical direction, by the factor a If a = 1 it is unchanged If 0 < a < 1, it is shrunk bt the factor a If a = 0, it is coincident with the x-axis If a < 0 then as above, but it is also reflected about the x-axis (turned upside down).
2sinx+1 equals 0
y = 1/2 x + 1
The function that is given has a constant value and therefore, its slope is 0.
