Answer:
Step-by-step explanation:
<u>Given function:</u>
It is a line with the slope of 1.
Average rate of change is same in any interval of the linear function and it equals to the rate of change or slope of the line.
You can calculate the average rate of change in the given intervals and you will always get the value of 1.
Answer:
20
Step-by-step explanation:
16-12/4+3(6-2) subtract 6 and 2
16-12/4+3+4 divide 12 and 4
16-3+3+4 subtract 16 and 3
13+3+4 add all 3 numbers
13+7
20
The answer is 78.
54/9 = 6
6x4 = 24
54+24 =78
The function notation f(x)=2x-4 means replace the x on the right-hand side with the value in parentheses on the left.
For example, f(y)=2y-4; f(4)=2(4)-4=4; f(1)=2(1)-4=-2 and so on.
The same principle applies to g(x), for example
g(2)=4(2^2)-3=13,
g(x+1)=4(x+1)^2-3=4(x^2+2x+1)-3=4x^2+8x+4-3=4x^2+8x+1
and so on.
(g of f)(x) is another way to write g(f(x)), therefore
g(f(x))
=g(2x-4) [because f(x)=2x-4
=4(2x-4)^2-3
=4(4x^2-16x+16)-3
=16x^2-64x+64-3
=16x^2-64x+61
