Given: r(x) = x3 - 7, k(x) = 5 ln (2x) Find: (k ○ r) (x)
sergij07 [2.7K]

The value of (k ○ r) (x) from the given parameters in the task content is; 5 ln(2x³ -14)

<h3>What is (k ○ r) (x) from the task content?</h3>

If follows from the task content that;

  • r(x) = x³ - 7 and k(x) = 5 ln (2x)

It therefore follows that;

(k ○ r) (x) = k(r(x)) = 5 ln (2(x³-7)).

On this note, the expression which represents (k ○ r) (x) is; 5 ln(2x³ -14).

Kryger [21]

Answer: Algebraically, linear functions are polynomial functions with a highest exponent of one, exponential functions have a variable in the exponent, and quadratic functions are polynomial functions with a highest exponent of two.

Step-by-step explanation: A linear equation is a type of equation in which the graph is straight and each term is a constant or a power of a constant. The formula is y=mx+b. Quadratic equations are similar to exponential equations by having a curve in the graph.

Which statement is true?
VLD [36.1K]
Hello there!


The answer is C.
-----------------------------------------------------------------------------------------------------

Explanation:


The value of 7 in 75 is 70. 

The value of 7 in 7.5 is 7

Now, we must find how many time 7 goes into 70

70/7 = 10

This means that The value of 7 in 75 is 10 times the value in 7.5


I hope I helped!

Let me know if you need anything else!
