Question

Use the graph of f(x) below to evaluate the following: 3 2 1 -4 43 -2 -1 1. 2 . 3 -1 -2 -3 1. f(-2) 2. f(1) 3. f(x) = 0

Answer 1

The f(-2) is the value of y at which the x =-2

In the given graph

at x =-2

The F(x) is at 1

Thus,

f(-2) = 1

2). f(1)

at x =1

the value st y is 1

So,

f(1)=1

3) f(x) =0

Here we have to find the value of x at which the y =0

So, when y=0 then the x =-1,4,-3

SO,

f(x)=0

then x = -1, -3, 4
