This question is incomplete; find the complete question in the attachment.
Given curve is modeled by the quadratic equation,
y = x²
If the curved pit is shifted 2 units down,
Equation of the translated curve will be,
y = x² - 2
If the curved pit is translated (shifted) by 2 units left,
Equation of the new curve will be,
y = (x + 2)²
If the curved pit is shifted by 2 units right,
Equation of the translated curve will be,
y = (x - 2)²
If the curved pit is shifted 2 units up,
Equation of the translated curve will be,
y = x² + 2
Explanation:
To determine the slope and y-intercept of the equation, let us plot the coordinates in the slope-intercept form.
Analyzing the graph, some of the points that are on the straight line is (1,0),(3,5), (9,20)
Let us consider the points (1,0),(3,5) to determine the slope.
Since, the profit is earned in thousands of dollars, m = 2.5 or m = 2500
Thus, slope = 2500
To determine the y- intercept, let us substitute any one of the coordinate from the graph.
Thus, let us substitute (1,0) in the equation to determine the y-intercept.
Simplifying, we have,
Hence, the line of best fit equation is
