2)Dada a função f: R - R definida por f(x) = ax² + b, com a, b E R, calcule a e b, sabendo que f(l) = 7 e f(2) = 22. Assinale a alternativa correta:

Given the parent function of [tex]f(x)=x^4[/tex], what change will occur when the function is changed to [tex]f(\frac{1}{2} x)[/tex]?

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
