Step-by-step explanation:
According to the graph, the function h(x) is the translation of the function f(x) to the right and down.
Compare the coordinates of the vertices to write the formula
- x = 6 - (-6) = 12
- y = 7 - 11 = - 4
The formula is
Answer:
The answer to your question is:
16.- x = -6
17.- x = -4; x = 2
18.- x = -5
Step-by-step explanation:
16.- 
x + 6 = 0(x - 4)
x + 6 = 0
x = - 6
17.- 
(x + 4) (x - 2) = 0)(x + 6)
(x + 4)(x - 2) = 0
x + 4 = 0 x - 2 = 0
x = - 4 x = 2
18.- 
2x + 10 = 0(3x - 12)
2x + 10 = 0
2x = - 10
x = - 10/2
x = -5
