778,300,000 in scientific notation

7 x 10^7

Step-by-step explanation:

count the zeros

7.783x 10 8th power

Step-by-step explanation:

Move the left

it will be 7.783

where the 8 came from?

from the amount of times the decimal has been moved

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

they can either have 0,1, or infinite solutions
