Answer:
120
Step-by-step explanation:
15*8=120
Collect like terms
2n2 i’m gonna assume is 2n^2
and n2 is 2n
2n^2-10n+5
The range is the output or the y values in the case of this function. The only y value on this function is 1 therefore the range is 1
Answer:
, the third one
Step-by-step explanation:
Explaining the sine function:
The sine function is defined by:

In which A is the amplitude,
is the period,
is the horizontal shift and V is the vertical shift.
So, in your problem:
The amplitude is 4, so A = 4.
The period is
, so
.
There is no horizontal shift, so
.
The vertical shift is −3, so V = -3.
The sine function that represents these following conditions is
, the third one
