Determine whether each function has a maximum or minimum value, and find that value. Then state the domain and range of the function.
7. f(x) = -32 + 6x - 1
3. f(x)=x2 + 3x - 12
9. f(x) = 3x2 + 8x + 5
10. f(x) = -472 + 10% - 6

7 has no minimum or maximum values. The range and domain is (−∞,∞).

3 has no maximum but has a minimum at (-1.5, -14.25). The doman is (−∞,∞) and the range is (-14.25, ∞).

9 has no maximum but has a minimum at (-4/3, -1/3). The domain is (−∞,∞) but the range is (-1/3, ∞).

I'm not sure if the % in question 10 is supposed to be an x, but I will assume it is. The function has no minimum or maximum, and the range and domain are both (−∞,∞).

Step-by-step explanation:

so what is the question

step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
