Answer: Choice A) The figure and its image are similar, but not congruent, and the image has been translated 1 unit up.

The jump from (x,y) to (2x,2y) means we dilated by a scale factor of 2. The image is twice as large as its original. There is no way the two figures are congruent (the larger image has longer side lengths). Despite congruence not being preserved, the two figures are the same shape, so they are similar figures. After the dilation is done, the "+1" tacked onto the "2y" means we shifted every point up 1 unit.

Identify the properties of the given quadratic.

Komok [63]

Answer:

see explanation

Step-by-step explanation:

A quadratic function in standard form is

y = ax² + bx + c (a ≠ 0 )

Given

y = - 3x² + 6x + 17 ← compare coefficients with standard form, then

a = - 3, b = 6, c = 17

Given the quadratic in standard form the the equation of the axis of symmetry is

x = - $\frac{b}{2a}$ = - $\frac{6}{-6}$ = 1

Equation of axis of symmetry is x = 1
