Answer:
f(-5) = 19
Step-by-step explanation:
Missing and incorrect;
f(x) = −3x + 4
x = −5
Find:
Solution of f(x)
Computation:
f(x) = −3x + 4
f(-5) = −3(-5) + 4
f(-5) = 15 + 4
f(-5) = 19
Answer:
x = ± 3, x = ± 2i
Step-by-step explanation:
Given
f(x) = (x² + 4)(x² - 9)
To find the zeros let f(x) = 0, that is
(x² + 4)(x² - 9) = 0
Equate each factor to zero and solve for x
x² - 9 = 0 ( add 9 to both sides )
x² = 9 ( take the square root of both sides )
x = ± = ± 3
x² + 4 = 0 ( subtract 4 from both sides )
x² = - 4 ( take the square root of both sides )
x = ± = ± = ± × = ± 2i
Thus zeros are
x = - 3, x = 3 ← real
x = - 2i, x = 2i ← complex
