Answer:
A
Step-by-step explanation:
When you derive a function from another using the transformation
you're translating the graph of the parent function f(x) horizontally.
More specifically, you translate the graph k units to the left if k is positive, k units to the right if k in negative.
So, starting from the graph of f(x), you have that the graph of
is the same graph of f(x), but shifted 3 units to the left.
Answer:
(3,4)
Step-by-step explanation:
x+y=7, where y=4, so therefore make x the subject and substitute y=4
x=7-y
x=7-4
x=3
therefore x=3, y=4.
The answer is the second number line.
Answer:
<em>A.</em><em> There were 400 larvae at 0 degree Celsius.</em>
Step-by-step explanation:
Here,
x = the temperature of water in °C
y = the number of insect larvae in the water
The graph is a graph of quadratic function as it is a parabola and it opens downward, so it has a negative leading coefficient i.e coefficient of x² is negative.
At y intercept, the line or curve passes through y axis. At y intercept the value of x is zero, because on y axis the value of x is 0.
As the y intercept in this case is (0, 400), so at y intercept value of x is 0 and y is 400.
Therefore, at y intercept or at 0°C there were 400 larvae.
