Answer:
x = -3
Step-by-step explanation:
x + x + x = 3 x
3 x + -3 = -12
-12 - -3 = 9
3x = -9
x = -9 ÷ 3 = -3
Assuming you want the inverse of f(x)=x²-2,
f(x)=x²-2
repalce f(x) with y
y=x²-2
switch x and y
x=y²-2
solve for y
x=y²-2
x+2=y²
√(x+2)=y
replace y with f⁻¹(x)
f⁻¹(x)=√(x+2)
the inverse is √(x+2)
X - y = 7
y = x - 7....the slope here is 1. A parallel line will have the same slope.
y = mx + b
slope(m) = 1
(1,0)...x = 1 and y = 0
now we sub and solve for b, the y int
0 = 1(1) + b
0 = 1 + b
-1 = b
so ur parallel line is : y = x - 1
