The roots of f(x) are {0, 3, -4}. You've got them as {-3, 4}, which is not correct.
Draw another set of coordinate axes and place dark dots at (0,0), (3,0) and (-4,0). These dots represent the roots (solutions) of the given polynomial.
Note that we have a repeated (double) root at x=3, which is given away by the exponent 2 of (x-3).
A basic way of sketching this graph is described as follows:
Evaluate the function (find y) for several x-values other than (0, 3 and -4):
Choose (for example) {-5, -2, -1, 1, 2, 4}
If you'll find the y-value for each of these x-values and plot the resulting points, you should see the shape of the graph. Draw a rough graph thru these points. If any doubt remains about what the graph looks like at particular x-values, calculate and plot more points, e. g., at {-2.5, -1.5, ...}.
If you're taking calculus, consider applying the First- and Second-Derivative tests to determine concavity, maximum, minimum, etc.

Answer:
Either increase the number of acres that can be used for strawberry fields (by buying more land)..If we use the same numbers from earlier, then the farmer should use approximately 16.65 acres of land (or just 17 acres of land)
So if the farmer has 17 acres of land or more, then he will make more than $70,000 per year
Step-by-step explanation:
Use the proportions from earlier
We have the point (5, 21000)
70,000/21,000 = 3.3
To find the x-value multiply 3.3 by 5
3.3 * 5 = 16.65
We can even use the other point's values to find the exact same answer
Point (3.5, 14700)
70,000/14,700= 4.7619047619
4.7619047619 * 3.5 = 16.66 (literally about the same)
Answer:
The length for on side is 10.5.
Step-by-step explanation:
6.5 + 6.5 = 13
34 - 13 = 21
21 divided by 2 is 10.5
Length 10.5 + 10.5 + 6.5 + 6.5 = 34
