What is the average rate of change of the function f(x) = 4x – 2 over the interval x = –1 and x = 2?

Alexeev081 [22]

Answer:

$4$

Step-by-step explanation:

Given: $f(x)=4x-2$

To find: average rate of change of the function $f(x)=4x-2$ over the interval $x=-1$ and $x=2$

Solution:

Take $a=-1,\,b=2$

Find $f(a),\,f(b)$

$f(a)=f(-1)\\=4(-1)-2\\=-4-2\\=-6\\\\f(b)=f(2)\\=4(2)-2\\=8-2\\=6$

Average rate of change of the function $=\frac{f(b)-f(a)}{b-a}$

$=\frac{f(2)-f(-1)}{2-(-1)}\\\\=\frac{6-(-6)}{3} \\\\=\frac{12}{3}\\\\=4$

Find the length of HJ

Free_Kalibri [48]

Answer:

Step-by-step explanation:

The equation:

2 + HI + 12 = 7 + 12

HI + 14 = 19 <em>subtract 14 from both sides</em>

HI = 5

HJ = HI + 12

Substitute the value of HI:

HJ = 5 + 12 = 17
