If f (x) = -x + 3
Then f (-3) = -(-3) + 3
f (-3) = 3 + 3
f (-3) = 6
Hope this helps!
Answer:
The domain is all real numbers. The range is {y|y ≤ 16}.
Step-by-step explanation:
The vertex of a parabola is given by
.
As a = -1, b = -2, c= 15 here, then the vertex is at (1,16).
As a is negative, it opens downward, so the range is {y|y ≤ 16}.
Meanwhile, all parabolic functions have a domain of 
.

The length of x is 33.85 when rounded to the hundredth place.
You can start solving this by using the tangent function.
Tan(Angle) = opposite/adjacent
Since the angle is 28 and the opposite side is 18, we can set adjacent as x and solve.
Tan(28) = 18/x ---> Cross multiply
xTan(28) = 18 ---> Divide by Tan(28)
x = 18/Tan(28)
Which equals roughly 33.85
