Question

12.) A photographer matts a print on a 14x 18 inch board. If the matt board is always in portrait mode with the 18 inch side vertical, write a function ffx) that can be valued at 14 for the side margin lengths which are equal and added to, the picture's horizontal dimension. 13.) Write another function fx) which can be valued at 18 for the top and bottom margins where the top margin must be 2/3rds the vertical spacing of the bottom one and these are added to, the picture's vertical dimension 14.) For a 1-1 function, can 2 unique values of the domain map to the same range value? A.) True) B.) False 15.) 2 answersOn a continuous function interval, and which of the following are true? A.) The function is ascending B.) The function is descending C.) is an absolute maximum for the entire function. D.) is a max but only for the isolated interval. 16.) 2 answers If resides in an interval such that and then is which of these? A.) Always an absolute maximum for the entire function B) At least a local maximum C.) At least a local minimum D.) A turning point where the tangent slope to will be zero. 17.) The slope of tangent lines just touching the outside edge of a curve reflect an instantaneous rate of change on the graph. What then is the value of the tangent slope at a minimum or maximum vertex? A.) Undefined B.) 90 degrees C.) approaching infinity D.) Zero E.) None 18.) What determines the average rate of change between 2 points on a continuous function in that interval? A.) slope of the asymptote B.) slope of a subtended angle's ray connecting 2 points which define the chord C.) slope of the secant line passing through the 2 given points D.) None

Answer 1

14) function is said to be one one if every element of domain has

Exactly one image in codomain.

So, there cannot be 2 unique values.

So, statement is false
