Unsure of what i need to do for question 1 and 2

f(1)=0; f(0)= -2; f(-1)=(-4); f(2)=2

Step-by-step explanation:

For the first four questions, f(1) means that x= 1, so you need to look at the graph, find the point where x= 1, and find the corresponding y value which is 0. You do this same process for each of the rest.

For 5 and 6: when they say f(x) = some value, this is the y value. So look at the graph: when y = 4, you can see that x = 3. When y = -6, you can see that x= -2.

where is the picture

step-by-step explanation:

it has to have an angle of 90 degrees
