Mathematics
1 answer:
ser-zykov [4K]2 years ago
3 0

Answer: b and d

Step-by-step explanation:

Since the roots are x=2 and x=6, we can write the equation as

f(x)=a(x-2)(x-6)

Substituting in the coordinates of the vertex,

-4=a(4-2)(4-6)\\\\-4=-4a\\\\a=1

So, the equation is f(x)=(x-2)(x-6)

On expanding, we get f(x)=x^2 - 8x+12

2. Find the bigger solution of the equation x2 - 11x = 0.
pickupchik [31]

Answer:

x\text{ = 11}

Explanation:

Here, we want to find the bigger solution

We can start by factoring x as follows:

\begin{gathered} x(x-11_)\text{ = 0} \\ x\text{ = 0 or x-11 = 0} \\ x\text{ = 0 or x = 11} \end{gathered}

The bigger solution is x= 11
