In two or more complete sentences, compare the number of x-intercepts in the graph of f(x) = x2 to the number of x-intercepts in the graph of g(x) = -x2 -5. be sure to include the transformations that occurred between the parent function f(x) and its image g(x).

Graph of f(x) has: 1 x-intercept.

Graph of g(x) has:  No x-intercept.

We know that a x-intercept of a function is a point on the graph where the value of function is zero.

i.e. it is a point where the graph meets the x-axis.

Hence, from the graph of the function f(x) we see that the graph has one x-intercept.

( Since, when we have:

Hence, x-intercept is:

(0,0) )

Now, when we have:

which is not possible as square of a real quantity can't be negative.

Hence, the function g(x) has no x-intercept.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

step-by-step explanation:

i'm not sure how to show the work for this

answer : c and d or 4(29 + 6)

4(29) + 4(6)
