Answer:
Option 2 is the correct answer
Step-by-step explanation:
A quadratic function is a function in which the highest power to which the variable is raised is 2
1) f(x) = −8x3 − 16x2 − 4x
The given function is a cubic function because the highest power
to which the variable,x is raised is 3
2) f(x) = 3x²/4 + 2x - 5
The given function is a quadratic function because the highest power
to which the variable,x is raised is 2
3) f(x) = 4/x² - 2/x + 1
It can be rewritten as
f(x) = 4x^-2 - 2x^-1 + 1
The given function is not a quadratic function because the highest power to which the variable,x is raised is - 2
4) f(x) = 0x2 − 9x + 7
It can be rewritten as
f(x) = - 9x + 7
The given function is not a quadratic function because the highest power to which the variable,x is raised is 1
this means alternate interior angle are congruent. to solve this, you would equal them together.
you would write out the equation, and then subtract 6x on both sides.
7x-7 = 6x+11
-6x -6x
this will give you
1x-7 = 11
you then add 7 on both sides
1x - 7 = 11
+ 7 +7
1x = 18
divide by 1 to solve for x
1x÷ 1
18÷ 1
x=18
