<u>Answer:</u>
y = 5x (x+2)
<u>Step-by-step explanation:</u>
We are given the following the quadratic function and we are to rewrite it in intercept or factored form:

We can factorize the given expression so taking the common factors out of it to get:


Therefore, the factored form of the given quadratic function is y = 5x (x+2).
Answer:
b. x = 0 ; (0,4)
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph
.
The equation is:
y=2*x^2+4
We can appreciate that the axis of symmetry corresponds to the y-axis, which is equal to the line x = 0
The vertex corresponds to the minimum point of the function.
V = (0,4)
Correct option: b.
