Answer:
- f(4) = -3
- x=-6 or x=0 for f(x)=1
Step-by-step explanation:
A. Find the point on the x-axis marked with a 4. Follow the vertical line down until it meets the blue line of the graph. At that point, follow the horizontal line to the left until it meets the y-axis at -3. This tells you ...
f(4) = -3

B. Find the point on the y-axis marked with a 1. Then find the x-values corresponding to the places where the horizontal line at y=1 intersects the blue curve. There are two of them: one at x=-6, another at x=0.
f(x) = 1 for x = -6 and x = 0

2. x =(-6+√-108)/18=(-1+i√<span> 3 </span>)/3= -0.3333+0.5774i</span><span>
3. x = 2/3 = 0.667</span></span>
The formula is Area = ( top + bottom)/2 * height
Using the image:
Area = (20 + 14) / 2 * 9
Area = 34/2 * 9
Area = 17*9
Area = 153 cm^2
