F(x) = x2 - 5

Mathematics
1 answer:
Tcecarenko [31]3 years ago
8 0

Answer:

D

Step-by-step explanation:

Given that f(x) has domain { 2, 4, 7 }

Substitute the values from the domain into f(x) for the range

f(2) = 2² - 5 = 4 - 5 = - 1

f(4) = 4² - 5 = 16 - 5 = 11

f(7) = 7² - 5 = 49 - 5 = 44

Thus the range is { - 1, 11, 44 } → D

Find the midpoint of the line segment joining the points P1 and P2.
ludmilkaskok [199]

Formula for midpoint between two points is M(x,y)

x=(x1+x2)/2 and y=(y1+y2)/2

In our case (x1,y1)=(m,b) and (x2,y2)=(0,0)

x=(m+0)/2=m/2 and y=(b+0)/2=b/2     M(m/2,b/2)

Good luck!!!
