When x = -2 h (x) = |-2x-6|

Mathematics
1 answer:
stich3 [128]3 years ago
4 0

Answer:

Step-by-step explanation:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

so you must first find what is the x and which one is the y in the function then you will find the answer when you solve the problem

Describe the error Sadie made, and explain how to find the correct answer.
ZanzabumX [31]

Answer:

The answer to your question is below

Step-by-step explanation:

Sadie should have left inside the root an exponent lower than the root and the power of "a" is higher than "2", the root is squared.

Right solution

\sqrt{54a^{7}b^{3}  }

54 = 3² 6

a⁷ = a⁶ a

b³ = b² b

                 = \sqrt{3^{2}6 a^{6} a b^{2} b }

                = 3a^{6/2} b^{2/2} \sqrt{6ab}

               = 3 a^{3} b \sqrt{6ab}
