The first one is graph c. The second is graph b.
Alex3 years ago
4 0

Answer:

C and B.

Step-by-step explanation:

f(x) = 4 - x^2.

The degree of f(x) is 2, which means it is a quadratic graph. The coefficient of x^2 is negative, which means the curve is pointing downwards. The only curve that satisfies this is Graph C.

f(x) = 2^x + 5.

Notice that 2^x is positive for all real values of x. Therefore the answer is Graph B.

Find the midpoint of (-8,-10) and (8,0)
Allisa [31]

Answer:

(0,-5)

Step-by-step explanation:

You just have to find the middle of each one

From -8 to 8 there are 16 numbers so you divide 16 by 2 which would be 8 and add that to -8 giving you 0

From -10 to 0 there are 10 numbers divided by 2 is 5 so you add 5 to -10 giving you -5

This makes your midpoint (0,-5)
