Which represents a quadratic function?f(x) = −8x3 − 16x2 − 4x

f (x) = x 2 + 2x − 5

f(x) = + 1

f(x) = 0x2 − 9x + 7

Answers

A quadratic function is one of the form f(x) = ax^2 + bx + c, where a, b, and c are numbers with a not equal to zero. In the given question, the only function that satisfies the condition of a quadratic function is f(x) = x^2 + 2x - 5 and thus is the correct answer to the question.

Answer:

f (x) = 3/4 x ^2 + 2x − 5

What is 4-6h-8h=60 answer

Answers

First you can subtract 6h-8h =-2h
4-2h=60
-4-2h=-4
------------
2h=56
Now divide and you get 56/2 =28

Solve the following system using the substitution method.9x + 8y = 15
-5x + 12y = -107

(x, y) = ( , )

Answers

x = (15 - 8y)/9

-5[(15 - 8y)/9] + 12y = -107

(-75/9) + (40/9) + 12y = -107

y = -8.59

x = [15 - 8(-8.59)]/9

x = 9.3
(x,y) = (9.3, -8.59)
