Answer:
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.
Answer:
x-5
Step-by-step explanation:
Because x>5, all values of the output will be positive, so the answer is x-5
Multiply all terms by 2 to get rid of fractions
2x+10=28-x
Add x to both sides
3x+10=28
Subtract 10 from both sides
3x=18
Divide both sides by 3
x=6
Final answer: x=6
