If f(x) = 2x2 - 5 and g(x) = 3x + 3, find (f - g)(x).

1 answer:

7 0

Answer: A. 2x2 - 3x - 8

Just subtract the functions and combine like terms
(f - g)(x) = f(x) - g(x)
(f - g)(x) = 2x^2 - 5 -(3x + 3)
(f - g)(x) = 2x^2 - 5 - 3x - 3
(f - g)(x) = 2x^2 - 3x - 8

Answer:

$7\frac{11}{35}$

Step-by-step explanation:

$2\frac{5}{7}+4\frac{3}{5}$

add the whole numbers

$2+4=6$

combine the fractions

$\frac{5}{7}+\frac{3}{5}$

LCM is 35 because 7 * 5 =35

$\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}$

$\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}$

$\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}$

$=\frac{46}{35}$

change the improper fraction into mixed number

$6+1\frac{11}{35}$

$=7\frac{11}{35}$
