Answer:

The two expression are 4x+3 and 4x+1.

Step-by-step explanation:

The given expression is

(3x-2x)+2(2x-x)+4

Simplify the given expression

x+2x+4

3x+4

The value of function at x=1 is

3(1)+4=7

The value of given expression is 7 at x=1. There many expression that gives the same value as (3x-2x)+2(2x-x)+4 at x=1.

The expression can be

4x+3

At x=1,

4(1)+3=7

The value of function at x=3 is

3(3)+4=13

The value of given expression is 7 at x=1. There many expression that gives the same value as (3x-2x)+2(2x-x)+4 at x=3.

4x+1

At x=3,

4(3)+1=13

Therefore the two expression are 4x+3 and 4x+1.

Answer:

g(-2) = -7

Step-by-step explanation:

To find g(-2), plug -2 into g(x).

g(x) = -4x² + 3x + 15

g(-2) = -4(-2)² + 3(-2) + 15

g(-2) = -4(4) + 3(-2) + 15

g(-2) = -16 + (-6) + 15

g(-2) = -1 + (-6)

g(-2) = -7

How is the graph of y=9(3)^x-2 -6 translated from the graph of y=9(3)^x ?
USPshnik [31]
For this case we have the following function:
 y = 9 (3) ^ x
 Applying the following transformations we have:
 Horizontal translations
 Suppose that h> 0
 To graph y = f (x-h), move the graph of h units to the right.
 y = 9 (3) ^ (x-2)
 Vertical translations
 Suppose that k> 0
 To graph y = f (x) -k, move the graph of k units down.
 y = 9 (3) ^ (x-2) - 6
 Answer:
 
2 units to the right
 
6 units down
