Which function has a range of all real numbers greater than or equal to -4?

max2010maxim [7]

Answer:

C. $f(x)=(x+1)^2-4$

Step-by-step explanation:

A. the graph is a straight line with slope 1. It goes up/down infinitely far so the range is all real numbers. Not A!

B. The graph is a straight line with slope -4, so, like the function in A, the range is all real numbers. Not B!

D. The graph is an absolute value function y = |x|, reflected over the x-axis, shifted right 3 units, then shifted down 4 units. So the graph starts witha "vee" shape opening up, becomes a vee opening down, then ultimately gets shifted down 4 units. The range is all real numbers less than or equal to -4.

See the attached graphs. image2 is the function in answer choice D.

there are a total of 1000 student are in tasha school.
Now, how many of the 1000 did participated in the said school sport event.
=> .600 x 1000
=> 600
Therefore, 600 out of 1000 students participated in their school sports event.
=> this is also equals to:

=> 6/10 x 1000
=> 6 / 1000
