Answer:
Step-by-step explanation:
When the scientists detect a signal frequency from the ocean floor, then the depth of submarine = feet
= feet
When they dive farther to check the signal, then the depth of the submarine= feet.
The net change in their elevation =
The given function is:
It is required to find the graph of g(x)=1/3 f(x).
Recall that the graph of a function g(x)=a f(x) is derived as a result of vertically shrinking the graph of f(x) towards the x-axis, where 0
Notice that in this case, a=1/3, which falls in the given interval for a vertical shrink.
Start with the graph of f(x)=x², which is the parent function for a quadratic function (graph in red):
Next, vertically shrink this graph towards the x-axis by a factor of 1/3 to graph, g(x)=1/3 f(x) in blue:
Notice that the graph that matches this from the options is the graph in option D.
The correct answer is option D.
Answer:
Step-by-step explanation:
step 1
Determine the slope of the dashed line
The formula to calculate the slope between two points is equal to
we have
(-3,1) and (0,3)
substitute
step 2
Find the equation of the dashed line in slope intercept form
we have
---> given problem
substitute
step 3
Find the equation of the inequality
we know that
Is a dashed line and everything to the left of the line is shaded
so
see the attached figure to better understand the problem
