Answer:
a). f(0) = 7
b). f(
) = 6
c). f(-5) = 22
d). x = 9
Step-by-step explanation:
The given function is f(x) = -3x + 7
a). For x = 0
f(0) = -3(0) + 7
= 0 + 7
= 7
b). For x =
f() = 
= -1 + 7
= 6
c). For x = (-5)
f(-5) = -3(-5) + 7
= 15 + 7
= 22
d). For f(x) = (-20)
-20 = -3x + 7
3x = 20 + 7
3x = 27
x = 9
Your answer would be 1234
Take the fouth square root of both sides
![\sqrt[4]{{x}^{4} } = \sqrt[4]{24}](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B%7Bx%7D%5E%7B4%7D%20%7D%20%20%3D%20%20%5Csqrt%5B4%5D%7B24%7D%20)
so
![x = \sqrt[4]{24} \: or \: x = - \sqrt[4]{24}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%5B4%5D%7B24%7D%20%20%5C%3A%20or%20%5C%3A%20%20x%20%3D%20%20-%20%20%5Csqrt%5B4%5D%7B24%7D%20)
