To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept - (3,0)
y-intercept - (0,12)
Slope: -4
Y-intercept: 12
The midline of the sine function is 0. The +3 added to the sine function moves the midline of f(x) to f(x) = 3.
_____
You may be expected to write the equation as y = 3.

Step-by-step explanation:
<u><em>Definition of: Coefficient</em></u>
A number used to multiply a variable.
<u><em>Example:</em></u> 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.
Variables with no number have a coefficient of 1.
<u><em>Example</em></u>: x is really 1x.
<em><u>coefficients:</u></em>
3<em>x⁴</em>+ 5<em>x²</em> + 1<em>x</em>
<u><em>sum of the coefficients:</em></u>
3 + 5 + 1
8 + 1
