Mathematics
1 answer:
laila [671]2 years ago
3 0

Answer:

4 (-1 + 2 x)

Step-by-step explanation:

Simplify the following:

9 x - (x + 4)

-(x + 4) = -x - 4:

9 x + -4 - x

Grouping like terms, 9 x - 4 - x = (9 x - x) - 4:

(9 x - x) - 4

9 x - x = 8 x:

8 x - 4

Factor 4 out of 8 x - 4:

Answer:  4 (-1 + 2 x)

The parent cosine function is transformed to create function d.
storchak [24]

Using translation concepts, it is found that the parent cosine function undergoes these following transformations:

  • Horizontal shift of 1 unit to the right.
  • Vertical shift of 5 units up.
  • The frequency was multiplied by 2.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent cosine function is given by:

f(x) = \cos{x}

The translated function is given by:

d(x) = \cos{(2x - 1)} + 5

The changes were as follows:

  • 1 was subtracted at the domain, hence it had a horizontal shift of 1 unit to the right.
  • 5 was added to the function, hence it had a vertical shift of 5 units up.
  • The domain was multiplied by 2, hence the frequency was multiplied by 2.

Change it into improper fraction to make it easier or just solve it as is.
=3\frac{5}{8}-2\frac{7}{8}
=\frac{29}{8}-\frac{23}{8}
=\frac{6}{8}=\frac{3}{4}            
OR
=3 \frac{5}{8}-2 \frac{7}{8}
divide it to two parts:
3-2=1 and \frac{5}{8}-\frac{7}{8}=\frac{-2}{8}
1\frac{-2}{8}⇒(1×8-2=6)
=\frac{6}{8}=\frac{3}{4}
