Rewrite each equation in the form of y= ax to the power of 2 + bx + c. Tell whether the equation represents a quadratic function.

1. y=2x- (-4) - 5× + 2

2. y= 4 (x to the power of 2 + 2)

3. y + 2 = -3(x to the power of 2 + 2x) -2x to the power of 2

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

the answer is b
