math
x+6=> if -5 less or equal to x < 1 9=> if x=1 -x+5=> if x>1 Sorry, still learing exactly how to post questions with the right signs the right way.

math
the function f is defined as the follows f(x)={x+6 if -5 less than or equal to x < 1 {9 if x = 1 {-x+5 if x > 1 a. find the domain of the function f is? b. locate any intercepts; if any please show work

calculus
solve the following inequality 15x-16 less than or equal to 15/x is the point x=0 included in the solution set of the inquality? are the other finite pointsa of the interval included in the solution set? what is the solution set? please show work

calculus
find the function that is finally graphed after the following transformations are applied to y=square root x in the order listed. a. reflected about the x-axis b. shift up 7 units c. shift right 5 units y=? would the answer be: y=sqrt(-x-5)-7

calculus
for the function f(x)=5/x+4, find the average rate of change of f from 1 to x. please show work

calculus
graph the following function using transformations. Be sure to graph all the stages on one graph. state the domain and range. y= -3/x/+1 NOT QUITE SURE HOW TO MAKE THE STRAIGHT UP AND DOWN LINE, INSTEAD OF THIS--/.

given the following piecewise function F(x)={x+11 for -9¡Üx<-3 2 for -3¡Üx¡Ü2 2x-6 for 2<x¡Ü5 {--this symbol is to be around all three of the lines. Find: a. the domain b. the range c. the intercepts d. if f continious on its d...

calculus
find an equation for the line with the given properties. express the equation in slope-intercept form containing the points. P=(-5,4) and Q=(-4,2) plz show work

calculus
find the distanced(p_1&P_2) between points P_1 and P_2. P_1=(4,-5) and P_2=(3,4) plz show work

trigonometry
A 100-foot vertical antenna is on the roof of a building. From a point on the ground, the angle of elevation to the top and the bottom of the antenna are 51 degrees and 37 degrees, respectively. Find the height of the building to the nearest foot. How would you solve for these?
