B. It is vertically stretched by a factor of 4. If you had x^2 versus 4x^2, when x is positive and increasing, 4x^2 is increased by 4 for every value of x.

Could I possibly get help with this?

ad-work [718]

Answer:

? = 74.64111442

Step-by-step explanation:

$\frac{sin(x)}{27}$ = $\frac{sin(90)}{28}$

= $\frac{1}{28}$

*27

= $\frac{27}{28}$

$sin^{-1}$ (27/28)

=74.64111442

Identify the domain and range of y = 4x - 5 + 3

Zepler [3.9K]

Answer:

$\huge\boxed{\text{Domain:}\ D=\mathbb{R}=(-\infty;\ \infty)}\\\boxed{\text{Range:}\ R=\mathbb{R}=(-\infty;\ \infty)}$

Step-by-step explanation:

y = 4x - 5 + 3 = 4x - 2

It's an equation of a line in the slope-intercept form.

y = 4x - 2 → f(x) = 4x - 2 - it's a lienar function.

The domain of a linear function is the set of all real numbers.

If a slope of linear function is different than 0, then the range is the set of all real numbers.
