What is the vertex of the graph of f(x) = |x + 3|+ 7? (3,7) (7,3) (-3, 7)(7,-3)

vertex (-3 , 7)

Step-by-step explanation:

vertex (h, k)     f(x) = a | x - h | + k

f(x) = |x + 3|+ 7 ,    h = - 3 and k = 7

vertex (-3 , 7)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
