The x-intercepts are -6 (put the radical over the 6) and 6 (put the radical over it) or if you need the simplified version they are -2.44 and 2.44
Answer:
n=11
Step-by-step explanation:
n+1=4(n-8)
11+1=4(11-8)
12=4(3)
12=12
5578/68=82.029411764705882352941176470588
that would be rounded to 82.02 which is the answer
Standard form of a quadratic f(x) = ax^2 + bx + c
In a quadratic function you find the vertex using the formula x = -b/2a; once you find the x value, substitute it into the equation and solve for y.
To know if a parabola opens up or down you look at the coefficient of the x^2 term. If it is positive, the graph opens up; if it is negative, the graph opens down.
