Answer:

-1

Step-by-step explanation:

When you have f(x) =- x^2 +3 and want to find f(-2), it is basically asking you to calculate the function where x is -2. So if you plug in -2 for x you get:

-(-2)^2 + 3= f(-2)

-4+3= f(-2)

-1=f(-2)

5p−m=10 answer my question
nasty-shy [4]

Answer:

m = -10 + 5p

Step-by-step explanation:

-m = 10 - 5p

divide -1 to both sides

m = -10 + 5p

m = -10 + 5p
