Answer:
x>10
Step-by-step explanation:
4(2x + 2) + 12 > 100
Subtract 12 from each side
4(2x + 2) + 12 -12> 100-12
4(2x + 2) > 88
Divide by 4
4/4(2x + 2) > 88/4
2x+2 > 22
Subtract 2
2x+2-2 > 22-2
2x> 20
Divide by 2
2x/2 >20/2
x>10
For this case, what you should see is where the graph cuts the x-axis.
Notice that the graph cuts to the x axis in three different points.
Then the value of x that is in the domain of the function in this case is:
x = 1
For this value of x the function is zero.
Answer:
x = 1
I remember answering the same question, but you didn't attach any photos. But I remember that the answer is the first one.
I hope I helped. Stay safe and God bless!

It is never true because there is no sum
After 5 years, value doubles.
Hence after 5 years, value is 250 x 2 = 500
After another 5 years, value doubles.
500 x 2 = 1000
Ans: $1000
Method 2, using function given.
v(10) = 250 x 2(10/5) = $1000
