G(x) = x²
a) To find g(1) substitute with x = 1 at the function g(x)
∴ g(1) = 1² = 1
b) substitute with x = -2 at the function g(x)
∴ g(-2) = (-2)² = 4
c) substitute with x = -x at the function g(x)
∴ g(-x) = (-x)² = x²
d) substitute with x = 2y at the function g(x)
∴ g(2y) = (2y)² = 4y²
e) substitute with x = 2+h at the function g(x)
∴ g(2+h) = (2+h)² = h² + 4h + 4
10,10 and 20 cannot as 10+10=20 so there would be a triangle with no area.
The others can all be the sides of a triangle as 7+7>8, 7+6>11 and 2+8>9.
Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
In this case m is 1/2 and b is 2.
This means that the slope of this line is 1/2 and the y-intercept is (0, 2) or simply 2
Hope this helped!
