Explanation / Answer
1.
equation of line with slope m=1/4 through the point (2,-2)
y + 2 =1/4(x - 2)
y = 1/4 x - 5/2
2.
x2 = 8 - 6x
x2 +6x - 8 =0
x = - 3+ sqrt17 , x = -3 - sqrt17
3.
-sqrt(2+x) < 0
2 + x < 0
x < - 2
domain of function is for all value of x < - 2
range of f is "y < 0"
4.
f(x) = (x - 2)/(x2 -9)
x2 -9 = 0
x2 = 9
x = + 3
the domain is "all x not equal to –3 or 3".
