Replace x with 3 in the equation to get:
7^2/ 3^2 -2
7^2 changes to 49 and 3^2 changes to 9:
49/9-2
Simplify 9-2 to 7:
49/7
Divide 49 by 7:
7

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)
Answer:160
Step-by-step explanation:
10 x 16
One US dollar equals roughly .77 British Pounds, so 950x.77=731.5.
The answer is roughly 731.50 British Pounds.
