Answer:

C

Step-by-step explanation:

To find the appropriate equation, notice the red graph has shifted up about 6 units. This means that 3*2^x-3 which is shifted by -3 will move 6 up. -3+6= 3. This means the function will have +3. Only B and C are options. Now test a point. Notice the red function crosses the y-axis at about 5 or 6 when x=0.

g(x) = 2^x+3\\g(0) = 2^0+3\\g(0)=1+3\\g(0)=4

This function doesn't match.

f(0) = 3*2^0+3\\f(0) = 3*1+3\\f(0)=6

This function matches. Option C is correct.

Select all expressions that are equivalent to 4x+2(2x-5)-(3-5x)
Arada [10]

For this case we have the following expression:

4x + 2 (2x-5) - (3-5x)

Applying distributive property to the terms within parentheses taking into account that:

- * + = -\\- * - = +

We have:

4x + 4x-10-3 + 5x =

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

4x + 4x + 5x-10-3 =\\13x-13

Thus, an equivalent expression is:

13x-13

Answer:

13x-13

What is the domain of f(x) = (x + 2)2 – 1?
larisa [96]

Simplify

\\ \tt\Rrightarrow f(x)=(x+2)^2-1

\\ \tt\Rrightarrow f(x)=x^2+4x+2-1

\\ \tt\Rrightarrow f(x)=x^2+4x+1

The Domain is set of all real numbers

\\ \tt\Rrightarrow Domain\in R

LekaFEV [45]

Answer:

D

Step-by-step explanation:

A triangle is always determined by the names of its angles. If, for any reason, you wanted to label it by its side names(which I don't even think you can do but assuming you wanted to), you dont even have the names for all three sides here. So, it can only be d. A, X, and T are the three angle names for this triangle, so this is triangle ATX or AXT.
