F(x)=√(10-3x) find the formula

1 answer:

8 0

Let y=f(x)
y=sqrt(10-3x)
you want to make x the subject

square both sides
y²=10-3x
3x=10-y²
x=(10-y²)/3

now replace y with x
f^-1(x)=(10-x²)/3

What is the best estimate for the product of 289 and 7

Katarina [22]

I would estimate it as (300 x 7) = 2100

Then I would subtract (11 x 7) + 77 from that to get the exact answer of 2023
