Answer:

1. x+4x

2. 5x

3. 6\frac{7}{x}

4. 4x-2x+15

5. (6+x)^2

Step-by-step explanation:

To write expressions remember these key words:

  • a number is a variable like x
  • sum is +
  • difference and subtracted is -
  • quotient is ÷
  • product is ×
  • reciprocal means flip like \frac{1}{9}---> \frac{9}{1}
  • square is an exponent of 2 like x^2

1. x+4x

2. 5x

3. 6\frac{7}{x}

Remember a quotient would be \frac{x}{7}but the reciprocal is \frac{7}{x}.

4. 4x-2x+15

5. (6+x)^2

What is the average rate of change for this exponential function for the interval from x = 2 to x = 4?
Hunter-Best [27]

Answer:

The average rate of change over the interval is 120

Step-by-step explanation:

For a function f(x) the average rate of change over an interval [a,b] is given as;

f(b)-f(a)/b-a

in this case, a is 2 and b is 4

f(b) is 256 and f(a) is 16

Substituting these values in the equation for rate of change, we have;

(256-16)/(4-2) = 240/2 = 120
