Question

Which is the graph of f(x) = (4)x?

Answer 1

f(x)=4x

Explanation:

In order to make the graph of f(x)= 4x we will find out few coordinates first and then plot them on the graph. In order to find the coordinates we will find the values of f(x) for random values of x .

Let us see:

x=1 ; f(x) = 4(1) = 4

x=2 ; f(x) = 4(2)=8

x=0 ; f(x) = 4(0)=0

x=-1 ; f(x)= 4(-1) = -4

x=-2 ; f(x)=4(-2)= -8

Hence our coordinates are

(-2,-8) ; (-1,-4) ; (0,0) ; (1,4) ; (2,8)

Now we plot those coordinates on x - y plane and join them to make our line. Please see the graph in the attachment.
