graphs of more than one function\n$f(4)=\\square$\nif $g(x) = 2,x=\\square$\n$y = g(x)$\n$y = f(x)$
Answer
Explanation:
Step1: Find f(4)
Locate x = 4 on the x - axis for the function y = f(x). Then, find the corresponding y - value on the graph of y = f(x). Looking at the graph of y = f(x), when x = 4, the y - value is - 10. So f(4)=-10.
Step2: Find x when g(x)=2
Locate y = 2 on the y - axis for the function y = g(x). Then, find the corresponding x - values on the graph of y = g(x). The graph of y = g(x) is a parabola. When y = 2, we can see from the graph that the x - values are - 6 and 6.
Answer:
f(4)=-10; If g(x)=2, x=-6 or x = 6
