Supposef: zz is defined by f(x) = 2x^2 + 1. a. explain using the definition of onto functions why the function f is or is not an onto function b. explain using the definition of one-to-one functions why the function f is or is not a 1-1 function

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.
