HELP ME PLEASE!!!!!!

Mathematics
1 answer:
zalisa [80]3 years ago
3 0

Answer:

m=4/3

b=0

Step-by-step explanation:

m= is the slope, which is 4/3 and b is the y intercept, which is (0,0). The equation would be y=4/3x+0 but we do not have to include the 0 making it y=4/3x. The equation is proportional becuase it goes through the point (0,0) and it is linear as it is a linear line.

The graph of a function, ƒ( x), is plotted on the coordinate plane. Select two of the following functions that would move the gr
Alex17521 [72]

Answer:

The following functions would move the graph of the function to the right on the coordinate plane.

C) f(x-3)+1

G) f(x-5)

Step-by-step explanation:

We need to check for those functions which shows a horizontal shift of graph to the right.

Translation Rules:

Horizontal shift:

f(x)\rightarrow f(x+c)

If c>0 the function shifts c units to the left.

If c the function shifts c units to the right.

Vertical shift:

f(x)\rightarrow f(x)+c

If c>0 the function shifts c units to the up.

If c the function shifts c units to the down.

Applying rules to identify the translation occuring in each of the given functions.

A) f(x+2)-7

Translation: f(x)\rightarrow f(x+2)-7

The translation shows a shift of 2 units to the left and 7 units down.

B) f(x)-3

Translation: f(x)\rightarrow f(x)-3

The translation shows a shift of 3 units down.

C) f(x-3)+1

Translation: f(x)\rightarrow f(x-3)+1

The translation shows a shift of 3 units to the right and 1 units up.

D) f(x)+4

Translation: f(x)\rightarrow f(x)+4

The translation shows a shift of 4 units up.

F) f(x+6)

Translation: f(x)\rightarrow f(x+6)

The translation shows a shift of 6 units to the left.

G) f(x-5)

Translation: f(x)\rightarrow f(x-5)

The translation shows a shift of 5 units to the right.
