Question 982712: Please help me solve this problem:
Graph the following using intercepts. y= 2 sqrt(x+9)-4
Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
Upper branch of a horizontal parabola, concave to the right. Translated from reference position by 9 units to the left and 4 units downward. The reference function equation would be . You will find that instead of this vertex at origin, your given equation has vertex moved to (-9,-4).

The question was, or assigned task was to graph USING THE INTERCEPTS.
Let each variable be 0, one at a time, and solve for the other variable.

If y is 0,

-
Then this is the intercept (-5,0). This is seen on the graph, also can be helpful in making the graph.

If x is zero,

-
The y intercept, (0,2).
