Answer:
f(g(x)) = 9
Step-by-step explanation:
Given f(x) =x-7 and g(x)= x^2 find f(g(4))
To calculate composition, first calculate g(4).
<u>g(4) can be calculated by replacing x with 4 in the equation</u>
g(x) = x^2
g(4) = 4^2 = 16
To calculate f(g(4)), we have to replace x in equation with the value of g(4)
f(x) = x-7
f(g(x)) = g(x) - 7
f(g(x)) = 16 - 7
f(g(x)) = 9
Answer:
Slope-Intercept Form of a Line (y = mx + b)
Step-by-step explanation:
The slope-intercept is the most “popular” form of a straight line. Many students find this useful because of its simplicity. One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y-intercept can easily be identified or read off from this form.
Step-by-step explanation:
a is less than b which means
a<b
When we change the numbers to negative what happens is the -b is farther than -a to zero. Now, -b is less than -a. Whether, a number is smaller or larger is determined by the number's distance to zero. If the number is negative the farther the number the smaller it is. If the number is positive the farther the number the larger the number is.
Let us take an example
3<4
Now their opposites are
-4 and -3.
4 3 2 1 0 -1 -2 -3 -4
Now, it can be seen that -4 is farther hence -4 is smaller than -3.
