Answer:
Step-by-step explanation:
f(x) = x² + 1
g(x) = 2x - 1
1) f(- 1) = (- 1)² + 1
f(- 1) = 1 + 1 = 2
b) f(-2) + g(-3)
f(-2) = (- 2)² + 1
f(-2) = 4 + 1 = 5
g(-3) = 2 × - 3 - 1 = - 6 - 1
g(- 3) = - 7
f(-2) + g(-3) = 5 - 7 = - 2
c) 3f(x) + 2g(x)
= 3(x² + 1) + 2(2x - 1)
= 3x² + 3 + 4x - 2
= 3x² + 4x + 1
d) f(g(3))
g(3) = 2 × 3 - 1 = 6 - 1 = 5
f(g(3)) = 5² + 1 = 25 + 1
f(g(3)) = 26
e) g(f(3))
f(3) = 3² + 1 = 9 + 1 = 10
g(f(3)) = 2 × 10 - 1 = 20 - 1
g(f(3)) = 19

Step-by-step explanation:
4 times 3 equals 12
3 times 4 equals 12
12 times 1 equals 12
1 times 12 equals 12
Answer:
Careful with blank 2! 6 - y would actually give 4. Y-6 would give -4.

This transformation is a translation.
Answer:
$15.21
Step-by-step explanation:
The total cost will be the cost of the meal plus the tip.
The tip is 17% of the meal's price. Multiply 13 by 0.17, and you will have $2.21 as the tip.
$13 + $2.21 = $15.21
