Everywhere you see an x just plug in the number and then do the arithmetic.
]]>find f(2)
Find f(0)
Find f(-4)
Find f(1)
Can you help me solve these
]]>State the domain of y = x^2
State the range of y = x^2
I get the domain as R and the range as [0,∞)
State the domain of y = x^2 + 2
State the range of y = x^2 + 2
Domain is R and the range is all positive reals greater than or equal to 2.

State the range of y = x2
State the domain of y = x2 + 2
State the range of y = x2 + 2
State the domain of y = 2x2 + 3
State the range of y = 2x2 + 3
State the domain of y = x2 5
State the range of y = x2 - 5
State the domain of y = -x2
State the range of y = x2
Take 1 / 9 away from both sides.
Flip them both,
x = 3
For the last one:
Times both sides by 15x.
Divide both sides 4.
x = ( 14 / 4 ) = ( 7 / 2 )
