Using the quadratic equation instead of calculus, you can find the x coordinate of the vertex as it will be the midpoint of the two x coordinates of the zeros...
x=(-3±√-27)/2
x=-1.5±√-6.75
That the second term is imaginary does not matter because we will add or subtract this value from -1.5, thus the midpoint of the zeros, the x coordinate of the vertex is -1.5. And to find the value of y for the vertex we just find the value of y when x=-1.5
y(-1.5)=6.75
Since y>0, the vertex is above the x-axis.
6 cm
the diameter is two times the radius so the radius would be 12/2 which is
6 cm
2(-2) + 7
= -4+7
= 3
so when x = -2 y = 3
Yes

Answer:
B.) a line labeled g(x) that passes through points 0, negative 3 and 4, 5
Step-by-step explanation:
I graphed both equation on the graph below to find the description of the graph of g(x).
Answer:
x = 5
Step-by-step explanation:
vertical angles are congruent , so
∠ A = ∠ B , that is
5x - 1 = 4x + 4 ( subtract 4x from both sides )
x - 1 = 4 ( add 1 to both sides )
x = 5
