Let a be a rational number and b be an irrational number. which of the following are true statements? a. the sum of a and b is never rational b. the product of a and b is rational c. b^2 is sometimes rational d. a^2 is always rational e. √a is never rational f. √b is never rational

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

kbmflmklbhml; bmlzb; bdhzz

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
