Vertex of h(x)=−4x 2 +12x−7

Mathematics
1 answer:
san4es73 [151]3 years ago
4 0

Answer:

x = 1.5

Step-by-step explanation:

To get the vertex of a quadratic equation you can use the formula

x = -b/2a

where f(x) = ax² + bx + c

So you would get -12/2(-4)

-12/-8

x = 1.5

Then substitue x in the equation to find y. I won't be doing that here

A quadratic function is a function that has a degree of 2. This shows that there will be about 72 births for month 8

<h3>Quadratic functions</h3>

A quadratic function is a function that has a degree of 2. Given the quadratic function shown:

f(x) = x² + x

where

x is the total months

In order to use the function to predict the number of births for month 8, we will substitute x = 8 into the function as shown:

f(x) = x² + x

f(8) = 8² + 8
f(8) = 72 births

This shows that there will be about 72 births for month 8

Please help me!!!!

Hello!

For #1, the LCD is (A) 12 since both numbers go into 12 as their minimal number.

For #2, the missing number is (B) 4 because 1/4*4/4=4/16.

For #3, the answer is (B) 3 because you have to crossmultiply 20n(4*15) to find the answer.

for #4, the correct answer is (A) 4/5 is less than 5/6 because when converted into fractions with a common denominator, 24/30 is less than 25/30.

For #5, the LCD is 36; therefore, the answer is (A) because the fractions in the answer are properly converted to their new denominator.

I really hope I helped!
