What is the vertex of the parabola f(x)=-(x-3)^2+25

(3,25) is the vertex

Step-by-step explanation:

f(x)=-(x-3)^2+25

This equation is written in the form

y = a(x-h)^2 +k

Where (h,k) is the vertex of the parabola

(3,25) is the vertex

(3,25)

Step-by-step explanation:

In y = a(x - h)² + k,

(h,k) is the vertex

Similarly,

In f(x)=-(x-3)^2+25,

(3,25) is the vertex

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
