What is the product? 3.[ 1 -4 5 -7]

a. [3 -12 15 -21]
b. [4 -1 8 -4]
c. [3 12 15 21]
d. [4 -12 8 -21]

(a)  [3        -12         15        -21]

Step-by-step explanation:

Given;

3.[ 1 -4 5 -7]

The product of the function is calculated as;

3.[ 1 -4 5 -7] = [1 x 3   -4x3     5x3     -7x3]

                   = [3        -12         15        -21]

Therefore the correct option is "a"  [3        -12         15        -21]

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
