The transformation set of
values for function
is
this is an interval to which sine function maps.
You can observe that the interval to which
function maps equals to
.
So let us take a look at the possible options.
Option A states that shifting
up by
would result in
having an interval
which is clearly not true that means A is false.
Let's try option B. Shifting
down by
to get
would mean that has a transformation interval of
. This seems to fit our observation and it is correct.
So the answer would be B. If we shift
down by one we get
, which means that
and
.
Hope this helps :)
Part A: 75 and 8 are both coefficients in this case since both numbers are in front of a variable. D and W are two variables in this expression since they are letters that represent unknown numbers. 25 is the constant since that number does not change.
Part B: If Javier works for 5 days and installs 48 windows, he earns $784.
75d+8w+25
75(5)+8(48)+25
375+384+25
784
Part C: If Javier receives $40 for snacks instead of 25, the constant would change since 25 was the constant to begin with. The rest of the expression would stay the same. The new expression would look like this: 75d+8w+40.
I hope this was helpful.
