The difference is that each number that comes after gets multiplied by 4
Hope I helped
Answer:
Step-by-step explanation:
Area = length * width
length: x + 3
width: x - 5
A = (x + 3)(x - 5)
Simplify (x + 3)(x - 5) using the FOIL method:
1. First numbers: multiply the first number of each binomial together--x*x = x%5E2
2. Outer numbers: multiply the outer number of each binomial (out of the entire expression, the number farthest to the left (x) and the number farthest to the right (-5))--x*-5 = -5x
3. Inner numbers: multiply the inner number of each binomial--3*x = 3x
4. Last numbers: multiply the last number of each binomial--3*-5 = -15
==> Now, add all of the results together and combine like terms: x%5E2+-+5x+%2B+3x+-+15 = x%5E2+-+2x+-+15
Therefore, A = x%5E2+-+2x+-+15
The range is from the maximum point into infinity that is [4, infty) and the vertex is at (0, 4)
<h3>Vertex, domain and range of a function</h3>
The given graph is a parabola. It represents the graph of a quadratic equation.
From the shown graph, the parabola has a maximum point at (0, 4). This is also the vertex of the graph
The domain area values along the x-axis while the range lies on the y-axis. From the graph shown, the domain is [-2, 2] (x lies between -2 and 2)
The range is from the maximum point into infinity that is [4, infty)

Answer:
A. x=0 and x=4
Step-by-step explanation:
The roots of a quadratic function are the x intercepts of the parabola. In this case, the roots are 0 and 4 because the parabola intercepts the x axis twice in these points.
Your answer is A. x=0 and x=4

Answer:
Step-by-step explanation:
1/3 x (15 +6) = 1/3 x 21
1/3 x 21 can be translated into 21 divided by three
∴ 1/3 x 21 = 7
