The y-intercept is (0,-11)
Answer:
y - 4 = -(x - h)^2
Step-by-step explanation:
We begin with the stock function y = x^2. Its graph is a parabola with vertex at (0, 0) and opening up. The more general vertex form of the graph is
y - k = a(x - h)^2, where the point (h, k) is the vertex and 'a' determines the direction of opening as well as by how much the parabola is stretched vertically.
In this problem the vertex is (6, 4); that is, the vertex is shifted to the right by 6 units and upward from there by 4 units. The coefficient 'a' is -1, indicating that the graph opens downward.
So we have the equation y - 4 = -(x - h)^2. Without more information we cannot tell whether the graph is stretched vertically or not.
Answer: D. Subtracting 9 from each side
Step-by-step explanation:
Always start with numbers without variables first before doing anything with x. And make sure one side must not equal 0 unless you're doing polynomials.
Answer:
A=6x²
Step-by-step explanation:
A cube is an object which is three-dimensional. A cube has six square faces.
If the side length = x inches
The area of a square = x²
Therefore, the expression for the surface area of a cube(with 6 square faces) with a side length of x is given as:
A=6x²
