<h2>♪Answer : </h2>

»f(x) = 7x² - 3x + 7

find f(2) in f(x)

»f(2) = 7(2)² - 3(2) + 7

»f(2) = 7(4) - 6 + 7

»f(2) = 28 - 6 + 7

»f(2) = 29

find f(-1) in f(x)

»f(-1) = 7(-1)² - 3(-1) + 7

»f(-1) = 7(1) + 3 + 7

»f(-1) = 7 + 3 + 7

»f(-1) = 17

find f(0) in f(x)

»f(0) = 7(0)² - 3(0) + 7

»f(0) = 7(0) - 0 + 7

»f(0) = 0 - 0 + 7

»f(0) = 7

so, f(2) + f(-1) + f(0) is

29 + 17 + 7
= 53✅

What's the inverse of a 2x4 matrix?

balandron [24]

Mxn Matrices do not have an inverse solution for m ≠ n, so your 2x4 will not have a solution.

<span>Generally, inverting matrices is done through finding the determinant of the square matrix and then performing an operation on the matrix based on the size of the matrix. </span>

<span>Wikipedia has a good article on Matrix inversion, take a look there for more information.</span>

The slope is 2 because remember, y= mx+b
m= slope
the slope is always multiplied by x
