The graph of f(x) = x2 is shifted 3 units to the left to obtain the graph of g(x). Which of the following equations best describ
es g(x)?
2 answers:
When you add a positive value to the argument of a function, its graph shifts to the left, the same number of units added to the argument.
This is, the graph of f(x+a) is the graph of the function f(x) shifted a units to the left.
Then, g(x) is f(x+3) = (x+3)^2
we have
This is the equation of a vertical parabola open upward with the vertex at point
we know that
The graph of f(x) is is shifted units to the left to obtain the graph of g(x)
so
The rule of the translation is
Applying the rule of the translation at the vertex of the graph of f(x)
The vertex of the graph of g(x) is the point
therefore
<u>the answer is</u>
The equation of g(x) is equal to

Answer:
the slope is -1
Step-by-step explanation:
formula for slope is (y2-y1)/(x2-x1)
lets say (-2,-3) is (x2,y2)
-3-(-5)=2
-2-0=-2
2/-2=-1
YOu can solve this through ratio and proportion.
16 / (16 + 20) = (x - 3) / (2x + 2)
x = 35
length AC = x - 3
AC = X - 3 = 35 - 3
AC = 32
