Given that g(x)=x^2, find each of the following.

FinnZ [79.3K]

G(x) = x²
a) To find g(1) substitute with x = 1 at the function g(x)
∴ g(1) = 1² = 1

b) substitute with x = -2 at the function g(x)
∴ g(-2) = (-2)² = 4

c) substitute with x = -x at the function g(x)
∴ g(-x) = (-x)² = x²

d) substitute with x = 2y at the function g(x)
∴ g(2y) = (2y)² = 4y²

e) substitute with x = 2+h at the function g(x)
∴ g(2+h) = (2+h)² = h² + 4h + 4

Show all your work!Thank you!

First we should change these mixed numbers into improper fractions:

$12 \frac{4}{9}= \frac{112}{9}$

$1 \frac{7}{9}= \frac{16}{9}$

We can find the number of crates used by dividing the total amount of electrical supplies by the amount that each crate can hold:

$\frac{112}{9}$ / $\frac{16}{9}=\frac{112}{9}$ * $\frac{9}{16} = \frac{1,008}{144}=7$

So now we know that Otto used 7 crates.
