Ignore the points and multiply, then you see that 4.12 has two decimal places and that 2.1 has one decimal place, when you add them there is three decimal places.

412 x 21 = 8652

4.12 x 2.1 = 8.652

Pls mark me as brainliest!!!!

The function f(x)=5x+4f(x)=5x+4 models the height of a tree, where x represents the years since the tree was planted for year 3

Romashka [77]

"all real numbers between 3 and 10 inclusive" could not be the answer, because these are x-values (values of the independent variable).

"all real numbers between 19 and 54 inclusive" is the range. Why? Because in year 3, f(3) = height of tree = 5(3) + 4 = 19 feet.

In year 10, f(10) = 5(10) + 4 = 54 feet.

What does the quadratic function f(x)=x^2-10x+9 look like when it is rewritten in the form f(x) = a (x-h) + k

Tatiana [17]

ANSWER

When $f(x)=x^2-10x+9$ is written in the form $f(x)=a(x-h)^2+k$ , it looks like $f(x)=(x-5)^2-16$
