<span>The equation given is f(x) = x^2 - 12x + 27
</span>
Based on its form, it is a parabola. First, factor the quadratic equation:

f(x) = (x-9) (x-3)

Plot in the x-y plane, assign values of x and solve for the values of y. 

x       y
1       16
2      7
3      0
0      27
-1     40
-2    55

Using the graph below, calculate the average rate of change for f(x) from
Annette [7]

Answer:

4

Step-by-step explanation:

Average rate of change = \frac{f(b) - f(a)}{b - a}

Where,

a = 0,

f(a) = f(0) = -2 (from the graph given)

b = 2,

f(b) = f(2) = 5 (from the graph)

Plug in the values

Average rate of change = \frac{5 - (-2)}{2 - 0}

= \frac{7}{2}

= 3.5 ≈ 4 (approximated)

Q: Wilma estimates that she’ll drive about 18,000 miles during the year. The car she wants to purchase gets an average of 24 mil
son4ous [18]

The mistake is made in the second step. The correct steps are given below.

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Wilma estimates that she’ll drive about 18,000 miles during the year.

The car she wants to purchase gets an average of 24 miles per gallon, and the average cost per gallon of gas in her neighbourhood is $2.72.

Locate the error in her calculations, and select the correction.

Step - 1

18000 miles/year

18000 miles / 12 months = 1500 miles/month

Step 2

1500 miles/month

1500 miles/month / 24 miles per gallon = 62.5 gallons/month

62.5 gallons/month

Step 3

(62.5 gallons/month) x ($2.72/gallons) = $170 cost/month
