The average rate of change of f(x)=3x+9 is 9. true or false?

1 answer:

7 0

The rate of change is the slope.
f(x) is the same as y...
f(x) = 3x + 9.....y = 3x + 9....and in y = mx + b form, the rate of change(slope) can be found in the m position.

y = mx + b
y = 3x + 9....so the slope or rate of change is 3...not 9...so answer is false

Such fractions are infinitely many, but will write you a few:
We extend a fraction of ten:
$\frac{1*10}{4*10}=\frac{10}{40}$
Our expressions must be in the range of 0, and $\frac{10}{40}$
$\frac{1}{40}$

$\frac{2}{40}$

$\frac{3}{40}$

$\frac{4}{40}$

$\frac{5}{40}$

$\frac{6}{40}$

$\frac{7}{40}$

$\frac{8}{40}$

$\frac{9}{40}$

Answer: y = 3x + 4

Explanation: The slope is positive 3x and the y-intercept is +4 therefore the equation is y = 3x + 4 in y = mx + b form.

(mx is for slope, b is for y-intercept)

Hope this helps :)
