Answer:
See below. <u><em>I assume that (x) = 8x2 - 7x + 3 is really (x) = 8x^2 - 7x + 3</em></u>
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

Answer:
Rational number
Step-by-step explanation:
Rational numbers repeat and terminate. The square root of 9 is 3, and 3 is a whole number as well as a number that terminates, which makes it a rational number
Answer:
103
Step-by-step explanation:
We substitute x with 5:
![4(5)^2+3](https://tex.z-dn.net/?f=4%285%29%5E2%2B3)
Solve the exponent first:
![5^2 = 25](https://tex.z-dn.net/?f=5%5E2%20%3D%2025)
<em>Note: We are using order of operations (consecutively)</em>
- <em>Parentheses </em>
- <em>Exponents</em>
- <em>Multiplication</em>
- <em>Division</em>
- <em>Addition </em>
- <em>Subtraction</em>
Multiply:
25 * 4 = 100
Add:
100 + 3 = 103
Our answer is 103
