The graph represents the speed at which Pete’s marble travels.
AfilCa [17]

Answer:

B

Step-by-step explanation:

Here, we simply want to know who will reach the 6-foot mark sooner

Mathematically, we need to get the slope from the graph

Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds

So what this mean is that, in 4 seconds, the 6 ft mark will be reached

This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs

Now compare this with what Stephano has, which is 2.25 ft/ s

we can see that stephano is traveling at a better speed and will reach the 6 ft mark first

So the correct option is B

When f(x) is replaced with<br> f(x)+k, the graph that results is shown below <br> K=__?
serious [3.7K]

Answer:

k = 6

Step-by-step explanation:

Parent function of the given graph → f(x) = (x - 1)²

If the parent function is shifted 6 units up.

Equation of the translated function will be → g(x) = (x - 1)² + 6

g(x) = f(x) + 6

Therefore, k = 6 will be the answer.
