Answer:
f(-2) = -1
Step-by-step explanation:
One way of doing this is to substitute -2 for x in every place where x shows up:
f(x) = 4x + 3x^2 − 5 → f(-2) = 4(-2) + 3(-2)^2 − 5
→ f(-2) = -8 + 3(4) - 5, or f(-2) = 4 - 5, or f(-2) = -1

Answer:
Multiplication Symbols:
<u>1.</u><u> Times</u> ×
<u>2.</u><u> Dot</u> ⋅
<u>3.</u><u> Parentheses</u> ()
<u>4.</u><u> Variables next to each other</u> <em>ab</em>
Step-by-step explanation:
The symbols can be used like this...
Times: <em>a</em> × <em>b</em> = <em>c</em>
Dot: <em>a</em> ⋅ <em>b</em> = <em>c</em>
Parentheses:<em> </em>(<em>a</em>)(<em>b</em>) = <em>c</em>
Variables next to each other: <em>ab </em>= <em>c</em>
(0, 4)
(-1, -3)
(2, -3)
