Graphing Exponential Functions In Exercise, sketch the graph of the function.
denis23 [38]

Answer:

The graph of the function f(x) = (1/2)^2x + 4 is attached as image below.

Analysis:

We have two intersection points in the graph

The function f(x) = (1/2)^2x + 4  intersects the y-axis at points (0,4)

The function f(x) = (1/2)^2x + 4  intersects the x-axis at points (-16,0)

f(x) is positive for x>-`16

f(x) is negative for x<-`16

-2x^2+4x-1 from 6x^2+3x-9
kirza4 [7]

Answer:

8{x}^{2}  - x   - 8

Step-by-step explanation:

We want to subtract

- 2 {x}^{2}  + 4x - 1

from

6 {x}^{2}  + 3x - 9

We set up the subtracttion problem to get:

6 {x}^{2}  + 3x - 9 - ( - 2 {x}^{2}  + 4x - 1)

We expand the parenthesis to get:

6 {x}^{2}  + 3x - 9  + 2 {x}^{2}   - 4x  + 1

Group similar terms:

6 {x}^{2}   + 2 {x}^{2} + 3x- 4x  + 1 - 9

We simplify to get:

8{x}^{2}  - x   - 8
