F(x) = x² + 2x - 1
f(2) = 2² + 2 · 2 - 1 = 4 + 4 - 1 = 7
f(-2) = (-2)² + 2 · (-2) - 1 = 4 - 4 - 1 = -1
f(3) = 3² + 2 · 3 - 1 = 9 + 6 - 1 = 14
f(-3) = (-3)² + 2 · (-3) - 1 = 9 - 6 - 1 = 2
The range = {-1; 2; 7; 14}
Answer: You can use only common factor (3).
Step-by-step explanation:
12g²-27h²
3 . ( 4g² - 9h² )
If a point has the same x-coordinate as the origin, that means the point could be anywhere on the y-axis. This means it could be below the x-axis or above, but never on the x-axis. This means if you drew it on a coordinate plane, the point would always be traveling vertically on the y-axis.
Answer:
y = x+5
Step-by-step explanation:
First we find the slope
m = (y2-y1)/(x2-x1)
m = (7-3)/(2 - -2)
=(7-3)/(2+2)
= 4/4
= 1
The slope intercept form is
y = mx+b
y = x+b
Substitute a point in
7 = 2+b
Subtract 2 from each side
5 =b
y = x+5
