Answer:
Option B.
Step-by-step explanation:
If the cost of the house (y) is in thousands and area of the house is x ft².
Cost of the house is modeled by the equation given,
y = 0.06x + 60.5
By substituting the values in the line of best fit,
235 = 0.06x + 60.5
0.06x = 235 - 60.5
0.06x = 174.5
x =
x = 2908.33 ft²
x ≈ 2900 ft²
Therefore, Option B will be the correct answer.
The dlope-intercept form:
m - slope
b - y-intercept (0, b)
The formula of a slope:
We have two points from the graph
x-intercept: (-1, 0)
y-intercept: (0, - 1) → b = -1
Substitute to the formula of a slope:

EXPLANATION
The given functions are:
and
The following statements are true;
h(x) is the reflection of g(x) in the x-axis.
g(x) opens upwards while h(x) opens downwards
Both functions have their vertex and intercepts at the origin.
The x-axis is a tangent to both functions at x=0.
g(x) has a minimum point
h(x) has a maximum point.
