Ab contains the points a(–3, 3) and b(1, 4). yz contains the points y(–4, 7) and z(–2, y). ab and yz are perpendicular. find the value of the y-coordinate of point z.
a.
y = –1
b.
y = 1
c.
y = 8
d.
y = 15

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

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
