Express each function in words: f of x = 4x minus 3, and g of x = 4 left paren x minus 3 right paren
Express each function in words: f of x = the square root of x minus 2, and g of x = the square root of x, minus 2
Express each function in words: f of x = the fraction with numerator x squared plus 1 and denominator 4, g of x = the fraction with numerator left paren x + 1 right paren squared and denominator 4, and h of x = left paren the fraction with numerator x + 1 and denominator 4 right paren squared
