J(x) = 3 – x; j(x) = -5

x = 8

Step-by-step explanation:

If j(x) = -5

j(x) = 3 - x

-5 = 3 - x

x = 3 + 5

x = 8

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
