Given f(x) = 3 and g(x) = cos(x). What is lim [F(x) - g(x)]?

Flura [38]

Answer:

4

Step-by-step explanation:

$\lim_{n \to \ -\pi } (f(x) - g(x))\\\\ = \lim_{n \to \ -\pi } (3 - cos x)\\\\ = 3 - cos( - \pi) = 3 - cos(\pi)\\\\ = 3 - (-1) = 3 + 1 = 4$

Question in pic, will mark brainliest.

bulgar [2K]

Answer:

See explanation

Step-by-step explanation:

Consider triangles ABC and DEC. In these triangles,

$\overline{BC}\cong \overline {EC}$ - given
$\overline{AC}\cong \overline {DC}$ - given;
$\angle ACB\cong \angke DCE$ as vertical angles.

So,

$\triangle ABC\cong \triangle DEC$ by SAS postulate (two sides and angle between these sides of one triangle are congruent to two sides and angle between these sides of another triangle, so triangles are congruent).

Congruent triangles have congruent corresponding parts, hence,

$\overline{BA}\cong \overline{ED}$

A function of the form f(x)=ab^x is modified so that the b value remains the same but the a value is increased by 2. How do the

ANEK [815]

Answer:

The domain and range remain the same.

Step-by-step explanation:

Hi there!

First, we must determine what increasing <em>a</em> by 2 really does to the exponential function.

In f(x)=ab^x, <em>a</em> represents the initial value (y-intercept) of the function while <em>b</em> represents the common ratio for each consecutive value of f(x).

Increasing <em>a</em> by 2 means moving the y-intercept of the function up by 2. If the original function contained the point (0,x), the new function would contain the point (0,x+2).

The domain remains the same; it is still the set of all real x-values. This is true for any exponential function, regardless of any transformations.

The range remains the same as well; for the original function, it would have been $y\neq 0$ . Because increasing <em>a</em> by 2 does not move the entire function up or down, the range remains the same.

I hope this helps!
