Answer:
x > -1
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
From the graph we can see that our x-values span from -1 to infinity. Since -1 is open dot, it is not included in the domain:
(-1, ∞) or x > -1
B. No solution
y = 5x -12
point-slope form:
y - y1 = m(x-x1)
m= slope
m= (y2-y1)/ (x2-x1)
we have (4, 8) and (2,-2)
x1 = 4 y1= 8
x2= 2 y2= -2
m=( -2-8) / (2- 4)
m= -10/ -2
m= 5
so we have:
y - 8 = 5(x-4)
y - 8= 5x -20
y= 5x -20 +8
