Hector and Linh are working individually on a problem involving the function f(x)=x2−5. On a domain where f is invertible, Hector says that f−1(4)=3, and Linh says that f−1(4)=−3.

Is Hector correct? Is Linh correct? Justify your answer.

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer

angle addition postulate

2x=56

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
