Answer:

a). -6x³ - 12x²    b). -12     c). 12

Step-by-step explanation:

a). (g x f)(x) can also equal f(g(x))

= f (2x +4)

= -3x² (2x+4)

= -6x³ - 12x²

b). f(g(-1))

g(-1) = 2(-1) + 4

= -2 + 4

= 2

f(2) = -3x²

= -3(2)²

= -12

c). g(h(3))

h(3) = 3x-1/2

= 3(3) - 1 / 2

= 4

g(4) = 2x + 4

= 2(4) + 4

= 12

A quadrilateral has vertices A{11, -7), B(9,-4), C11,-1), and D(13,-4).
Bess [88]

Answer:

Quadrilateral ABCD is a <u>parallelogram</u>

if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a <u>kite</u>

Step-by-step explanation:

without solving, im guessing that quad ABCD is a paralellogram (//gram)

lets test this theory

see if the slope of AB and CD, and BC and AD is the same

slope AB and CD

AB:

-7--4/11-9

=-3/2

CD:

-1--4/11-13

=3/-2

=-3/2

slope is the same

slope BC and AD

BC:

-4--1/9-11

=-3/-2

=3/2

AD:

-7--4/11-13

=-3/-2

=3/2

slope is same

because 2 pairs // sides ---> //gram

if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a kite

hope this helps!

40points!!!! Describe how the graph of the function is related to the graph of f(x) + x^2
muminat

Answer:

  g(x) is f(x) translated downward by 7 units

Step-by-step explanation:

Adding a value to a function translates its graph upward by that value. Here, -7 is added, so the graph is translated downward by 7 units.

_____

This should be no mystery. When (x, y) is plotted on a graph, the y-coordinate specifies the vertical distance from the x-axis. Then (x, y-7) would specify a vertical distance that is 7 units less. That is, the point would be 7 units lower than the point (x, y) on the graph.
