Answer:
Domain = Range = All real numbers
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph
The equation is:
f(x)=2x+cos x
From the plot, we can see the answer is
Option a.
Domain = Range = (-∞,∞)
Answer:
Option D
Step-by-step explanation:
Rate of change of a linear function between two points and
is given by,
Rate of change 'm' =
From the given table,
Rate of change of the function between (-2, 6) and (-4, 9),
Rate of change 'm' =
m =
Initial value = y-intercept
Let the equation of the line passing through a point (h, k) is,
y - k = m(x - h)
If a point (-2, 6) is lying on the graph of the function,
y - 6 =
y =
y =
Y-intercept of the function = 3
Therefore, initial value of the function = 3
Option D is the answer.
