A quadratic has a squared term...causing the shape of a parabola, a U shape because both positive and negative x's squared end up being the same number. real world situation a quadratic could be used to track the height of a launched object. An exponential has the variable in the exponent, causing the y to grow or decay increasingly quickly or increasing slowly real world example: banks use interest, over months or years.Each time the interest is applied, it is applied to a new and bigger total
It’s a function because the number doesn’t repeat
-30-27= -57
When both numbers are negative, they are “added” in a sense, but remain negative.
-5-(-4)= -1
You have to multiply the (-4) by the “invisible” -1 on the outside before you add/subtract.
Since the sign before the parentheses is a + , we can just remove the parentheses.
