Suppose f is a function

If f(-4) = f(8) = 0, describe how this looks on a graph

Answe

     • The graph of 2g(3x) is obtained from the graph of g(x) by shrinking the horizontal coordinate by 1, and stretching the vertical coordinate by 2. (You’d get the same answer here if you reversed the order of the transfor- mations and stretched vertically by 2 before shrinking horizontally by 1. The order isn’t important.)  3  3       74 (x) 4, 7:— ‘I ‘I’ -I -4-I -t N I

Step-by-step explanation:

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
