Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -4x² + 6x - 4
f(5) is x = 5
<u>Step 2: Evaluate</u>
- Substitute: f(5) = -4(5)² + 6(5) - 4
- Exponents: f(5) = -4(25) + 6(5) - 4
- Multiply: f(5) = -100 + 30 - 4
- Add: f(5) = -70 - 4
- Subtract: f(5) = -74

= 2
+ 3 ![\left[\begin{array}{ccc}1&-1\\-6&3\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%26-1%5C%5C-6%263%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Multiply each element in the matrices by the scalar quantity, that is

Answer:
$17
Step-by-step explanation:
This is simply stated as a function.
We can rewrite this problem out as --> f(d) = -d + 42
If we simply say that he spent d, the problem states that d is equivalent to 25.
So the function looks like this --> f(d) = -25 + 42
Therefore your answer becomes --> f(d) = 17
