HURRY! The function f is defined below. What is the value of f(-3)?
f(x)=x^2+2x-7

-22
-10
-7
-4
8

y=mx+b

step-by-step explanation:

m slope

b y-intercept

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

ok thats very interesting
