Question

make a scatterplot of the data and graph the function on the same coordinate grid. calculate the residuals and make a residual plot. describe the fit of the function to the data.
$f(x) = 2x^2 - 2x + 1$

$x$	$y$
$-1$	$-3$
$0$	$-6$
$1$	$-3$
$2$	$2$

make a scatterplot of the data and graph the function on the same coordinate grid. choose the correct answer below.
a.
graph a
b.
graph b
c.
graph c
d.
graph d

Explanation:

Step1: Plot data points

Points: $(-2,6), (-1,-3), (0,-6), (1,-3), (2,2)$

Step2: Graph the quadratic function

Function: $f(x)=2x^2-2x-6$

Step3: Match to correct option

Verify that option A shows both the plotted data points and the correct parabola shape of $f(x)=2x^2-2x-6$ on the same grid.

Answer:

A
