Evaluate the function g(x) = –2x2 + 3x – 5 for the input values –2, 0, and 3.

Genrish500 [490]

Answer:

g(-2) = -15, g(0) = -9, g(3) = -18

Step-by-step explanation:

g(-2) = -2*2 + 3(-2) - 5 g(-2) = -4 - 6 - 5g(-2) = -15g(0) = -4 - 0 - 5g(0) = -9g(3) = -4 - 3(3) - 5g(3) = -4 - 9 - 5g(3) = -18

2. Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral A'B'C'D. Which rule best rep

Virty [35]

Answer:

$(x,y) => (2.5x,2.5y)$

Step-by-step explanation:

Given

See attachment for ABCD and A'B'C'D'

Required

Determine the dilation rule

Using AB and A'B' as points of references;

$AB = (-1,2)\ to\ (2,1)$

$A'B' = (-2.5,5)\ to\ (5,2.5)$

The dilation factor (k) is calculated as:

$k = \frac{A'B'}{AB}$

This gives:

$k = \frac{(-2.5,5)}{(-1,2)} \ or\ k = \frac{(5,2.5)}{(2,1)}$

Factorize

$k = \frac{2.5*(-1,2)}{(-1,2)} \ or\ k = \frac{2.5*(2,1)}{(2,1)}$

$k = 2.5 \ or\ k = 2.5$

Hence, the scale factor is 2.5

The dilation rule is:

$(x,y) => k(x,y)$

$(x,y) => 2.5(x,y)$

$(x,y) => (2.5x,2.5y)$
