For the following exercises, evaluate the function f at the values f(−2), f(−1), f(0), f(1), and f(2)

MatroZZZ [7]

Answer:

See below. I assume that (x) = 8x2 - 7x + 3 is really (x) = 8x^2 - 7x + 3

Step-by-step explanation:

Substitute the value of x given in f(x) into the equation f(x) = 8x^2 - 7x + 3

For example, f(0) would be f(0) = 8(0)^2 - 7(0) + 3. f(0) = 3

f(-2) would be f(-2) = 8(-2)^2 - 7(-2) + 3.

= 8*4 + 14 +3

= 32 + 17 therefore f(-2) = 49

Twenty times y is at most 100 in interval notation

DiKsa [7]

Answer:

$y\in (-\infty ,5]$

Step-by-step explanation:

In this problem, we need to write "Twenty times y is at most 100 in interval notation ".

20 times y means, 20y

Atmost means an inequality which is $\le$

ATQ,

$20\times y\le 100$

i.e.

$20y\le 100\\\\y\le 5$

We can also write it as :

$y\in (-\infty ,5]$

Hence, the required interval notation is $y\in (-\infty ,5]$ .
