Answer:

x = - $\frac{3}{4}$

Step-by-step explanation:

Multiply through by 4 to clear the fraction

15 - 28x = 36 ( subtract 15 from both sides )

- 28x = 21 ( divide both sides by - 28 )

x = $\frac{21}{-28}$ = - $\frac{3}{4}$

Determine algebraically whether the function is even, odd, or neither. f(x = -5x2 4

Sunny_sXe [5.5K]

What you said doesn't even make sense.

I'll assume you said f(x) = -5x^2 + 4.

This is an even function.

f(-x) = f(x)

Option C: -3 is the average rate of change between $x=-1$ and $x=1$

Explanation:

The formula to determine the average rate of change is given by

Average rate of change = $\frac{y_2-y_1}{x_2-x_1}$

We need to find the average rate of change between $x=-1$ and $x=1$

Thus, from the table, we have,

$x_1=-1$ , $y_1=5$

$x_2=1$ , $y_2=-1$

Thus, substituting these values in the formula, we get,

Average rate of change = $\frac{-1-5}{1+1}$

$=\frac{-6}{2}$

$=-3$

Thus, the average rate of change between $x=-1$ and $x=1$ is -3.

Hence, Option C is the correct answer.

stira [4]

Answer:

Continuous data are data which can take any values. Examples include time, height and weight. Because continuous data can take any value, there are an infinite number of possible outcomes.
