Answer:
(- 2, - 9 )
Step-by-step explanation:
The axis of symmetry passes through the vertex of the parabola.
Thus the x- coordinate of the vertex is x = - 2
To find y substitute x = - 2 into f(x)
f(- 2) = (- 2)² + 4(- 2) - 5 = 4 - 8 - 5 = - 9
Vertex = (- 2, - 9 )
Answer:
n= 1
x= 2
Step-by-step explanation:
the equations are 2n - x = -1
2x + 3n = 9
<span>F(x) = 4x -1
Substitue 3 for x
F(3) = 4(3)-1
Multiply 4 by 3
F(3) = 12-1
Subtract
Final Answer: F(3)= 11</span>
