Answer:
The graph is not a function of x because x=0 intersects the graph at two points.
Step-by-step explanation:
The vertical line test is when you draw, well, a vertical line through the graph. the slope of a vertical line is undefined, and the formula written as x=_. So we can eliminate the choices with y=_.
We can clearly see that this graph isn't a function, so we can eliminate the answer choices that say that the graph is a function.
Just in case, draw a line at x=0, to check that it does indeed cross the graph in 2 places.
Answer: 300 years
Step-by-step explanation:
Let x be the age of Florentine statue,
Thus, According to the question,
The age of Roman statue = 3 x
After 100 years, the age of Florentine statue = x + 100
And, the age of Roman statue = 3x + 100
Again according to the question,
3x + 100 = 2( x + 100)
3x + 100 = 2x + 200
3x - 2 x = 200 - 100
x = 100
Therefore, the present age of Roman statue = 3 × 100 = 300 years
