Teaching properties of functions is foundational in Algebra 1. Read some of our tips and tricks for having students master this concept.
Thedomainof a function is the set of values which you are allowed to put into the function (so all of the values that x can take). Therangeof the function is the set of all values that the function can take, in other words all of the possible values of y when y = f(x). So ...
Step 1: y = 4x - 7/4. Step 2: Interchange x and y and find y in terms of x. Step 3: x = 4y - 7/4 [Interchange x and y.] Step 4: 4x = 4y - 7 [Multiply throughout by 4.] Step 5: 4x + 7 = 4y [Add 7 to both sides of the equation.] Step 6: 4x + 7/4...

This problem goes “backwards” (outside in), where we need to first find the “$ x$” (different than the $ x$ in the problem – sorry!) where $ g\left( x \right)=5$. Note that we get two cases: $ \begin{align}g\left( x \right)&=5\\3{{x}^{2}}+4x+1&=5\\3{{...

f( f-1(11) ) = 11 "f of f inverse of 11 equals 11"Solve Using AlgebraWe can work out the inverse using Algebra. Put "y" for "f(x)" and solve for x:The function: f(x) = 2x+3 Put "y" for "f(x)": y = 2x+3 Subtract 3 from both sides: y-3 = 2x Divide both sid...
