Answer:
y = -(x + 5)^2 + 4
Step-by-step explanation:
I'm 8 years old and I know how to do this.
Y=|2x|
x=|2y|
x=2y
x/2=y
f^-1(x)=x/2
Answer:
y = x + 8
Step-by-step explanation:
find slope first:
m = 7-5 / -1-(-3)
m = 2 / 2
m = 1
now find the y-intercept using either ordered pair; plug 'y', 'x', and 'm' into
y = mx + b to solve for 'b'
7 = 1(-1) + b
7 = -1 + b
8 = b
put 'm' and 'b' into slope-intercept equation of a line, y = mx + b to get:
y = x + 8
