Answer:
use desmos it will help you with plots
Step-by-step explanation:
just search desmos
To transform the function
to have the amplitude of 3, we need to multiply the constant 3 to the function f(x), so we have
To transform the function
to have the midline
we need to subtract
by 4, so we have
,
To transform the function
to have period of
, we need to divide the original period
by 4, so we have
. Note that it is the
gives the effect of dividing the points on x-axes by 4 and the period is read on x-axes
Hence, the full transformation is given
which is the last option
3 times. Draw a line 1 unit up, and you can see that there are 3 intersections.
Since we know the value for c and d we just plug them into the equation which will look like this. 6•5^2-5•4+8
Answer: 138
