Given the function fx 7x2 14x 4 if x 1 what is fx What p

Given the function f(x) = -7x^2 + 14x + 4, if x = 1, what is f(x)? What point is on the graph of f? 11; (1, 11) 11; (11, 1) -17; (1, -17) -17; (-17, 1) Based on the graph, find the range of y = f(x).

Solution

given f(x) = -7x^2 +14x +4

If x = 1 then

f(x) = -7 + 14 +4 = 11

The point on the graph of f is (1,11)
