inna [77]

Answer:

Probability that the 8th grader is a boy = 5/(5+7) = 5/12

Given that (-3 3) is on the graph of f(x) find the corresponding point for the function f(x+1)
vredina [299]

Answer:

(-3, 4).

Step-by-step explanation:

When f(x) becomes f(x + 1), all that is happening is that the y-value increases by 1.

So, (-3, 3) becomes (-3, 3 + 1). That is (-3, 4).

Hope this helps!
