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:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
