The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function? f(–3) = –5

f(–3, –5) = –8

f(–5) = –3

f(–5, –3) = –2

step-by-step explanation:

step-by-step :

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
