A function for which every element of the range of the function corresponds to exactly one element of the domain. ... Note: y = f(x) is a function if it passes the vertical line test. It is a 1-1 function if it passes both the vertical line test and the horizontal line test.
A one-to-one function is a function in which the answers never repeat.
Answer:
{0,1,2,3}
because whole numbers always starts from zero...
Make x the subject means you need to solve for x
y = ax^2 solve for x
divide both side by a
y/a = ax^2/a
simplify
y/a = x^2
so
x = square root (y/a)
We will use the distributive property. -4 times 9z=-36z -4 times -2=8 so we have -36z+8 as our answer
