Question

Using complete sentences, explain the difference between a linear equation and a quadratic equation.

Answer 1

Linear Function: A function with no exponents other than one and with no products of the variables (eg, y=x+4, y= -4, and 3x-4y = 1/2 are linear functions); in a rectangular coordinate system, the graph of a linear function is a line. It is a function that has a constant rate of change. It has a graph which is a straight line.Such a function can be written as f(x) = mx + b, where m and b are real constants and x is a real variable.

Quadratic function: A quadratic function, in mathematics, is a polynomial function of the form y = ax^2+bx+c,where, a is not equal to "0",where a, b, and c are arbitrary, but fixed. A quadratic function is also referred to as a degree 2 polynomial or a 2nd degree polynomial, because the highest exponent of x is 2. The graph of this function is a parabola.

Answer 3

Thanks so much!

Answer 4

no problem, medal thanks :D

Answer 5

How can I word this different and shorters than that

Answer 6

Linear equation: graphs a straight line

Quadratic equation: graphs a "bowl" shaped curve


That's the basic visual difference

Answer 7

In terms of algebra, a linear equation has one x-intercept and this is always true. On the other hand, a quadratic equation can have 0, 1 or 2 x-intercepts (depending on the equation)

Answer 8

What do the equation look like?

Answer 9

Linear equation:

Answer 10

written

Answer 11

Ex:

Linear equation: y = 2x+3

Quadratic: y = x^2+4x-5

Answer 12

Whats the Quadrtic with the letters?

Answer 13

\[Quadratic : y = x ^{2} + 4x -5\]

Answer 14

oh it's y = ax^2+bx+c

Answer 15

y = ax^2+bx+c is the base equation.

Answer 16

just like the linear equation y = ax + b
