Chapter 2: Q. 85 (page 70)

If f(x)=3x+82x-Aand f(0)=2, what is the value of A?

Short Answer

Expert verified

The value ofA=-4

Step by step solution

01

Step 1. Given Information 

If f(x)=3x+82x-Aandf(0)=2

We have to find the value of A.

02

Step 2. To find the value of A we firstly find the f(0) by putting x=0 in the given function.

f(0)=3脳0+82脳0-Af(0)=8-Af(0)=-8A

03

Step 3. Now the function is f(0)=-8A.We know f(0)=2 so we put the value of f(0) in the function.

2=-8A

Multiply with Aon both side

2脳A=-8A脳A2脳A=-8

Divide by 2 on both side

22脳A=-82A=-4

A function f is ___________ on an open interval I if, for any choice of x1 and x2 in I, withx1<x2wehavef(x1)<f(x2)

Exploration Graph y=x3,y=x5, and y=x7 on the same screen. What do you notice is the same about each graph? What do you notice that is different?

In Problems 7鈥�18, match each graph to one of the following functions:

A.y=x2+2B.y=-x2+2C.y=x+2D.y=-x+2E.y=(x-2)2F.y=-(x+2)2G.y=x-2H.y=-x+2I.y=2x2J.y=-2x2K.y=2xL.y=-2x

Graph y=x. Then on the same screen graph y=2x, followed by y=4x, followed by

y=12x.What pattern do you observe? Can you predict the graph ofy=14x? ofy=5x

?
