I'm pretty sure it would be y=2x+9
Answer:
she will be responsible with a big bill to pay that's for sure
In this question, we have a graph given. And using that graph we have to find the value of f(1) .
f(1) means the y value when x=1 .
So we need to check the value of y at x=1 .
And if we follow the graph, we will see that at x=1, y=2.5 . So the value of f(1)=2.5 and that's the required answer .
