Given the tables for f &amp; g below, find the following: x f ( x ) g ( x ) 0 9 7 1 4 8 2 3 6 3 5 1 4 7 5 5 1 2 6 6 0 7 0 4 8 2

\\(i)\\&#10;\text{We know that the average rate of change of a function f(x) on inerval [a,b] is}\\&#10;\\&#10;f_{avg}=\frac{f(b)-f(a)}{b-a}\\&#10;\\&#10;\text{so using this the average rate of chang of g for x on interval }[3,7] \text{ is}\\&#10;\\&#10;g_{avg}=\frac{g(7)-g(3)}{7-3}\\&#10;\\&#10;=\frac{4-1}{4}\\&#10;\\&#10;=\frac{3}{4}\\&#10;\\&#10;\text{so average rate of change of g on interval [3,7] is }\frac{3}{4}

\\(ii)\\  \text{Average rate of chang of f for x on interval }[3,7] \text{ is}\\&#10;\\&#10;f_{avg}=\frac{f(7)-f(3)}{7-3}\\&#10;\\&#10;=\frac{0-5}{4}\\&#10;\\&#10;=\frac{-5}{4}\\&#10;\\&#10;\text{so average rate of change of g on interval [3,7] is }\frac{-5}{4}

\\(iii)\\&#10;\text{Since g(4)=5, so we have}\\&#10;\\&#10;f(g(4))=f(5)\\&#10;\\&#10;\text{since the value of f is 1 at x=5. so }\\&#10;\\&#10;f(g(4))=f(5)=1\\&#10;\\&#10;\text{hence we have, }f(g(4))= 1

\\(iv)\\&#10;\text{Since f(3)=5, so we have}\\&#10;\\&#10;g(f(3))=g(5)\\&#10;\\&#10;\text{since the value of g is 2 at x=5. so }\\&#10;\\&#10;g(f(3))=g(5)=2\\&#10;\\&#10;\text{hence we have, }g(f(3))= 2

Which graph represents the linear function y= -5x + 2
Semmy [17]
Look at all the options... the correct one should have a negative slope (so it would be a line decreasing), and it should also intersect on the Y axis at 2.

Write and solve an equation twice a number is 26​
Svet_ta [14]

Answer:

2x = 26, x = 13

Step-by-step explanation:

Write and solve an equation twice a number is 26

x = unknown number

Equation: 2x = 26

Solve:

2x = 26

/2    /2 <== divide both sides by 2

x = 13

Check your answer:

2x = 26

2(13) = 26

26 = 26

This stament is correct

Hope this helps!
