The functions f and g are defined as follows
f(x)=-5x+2 g(x)=3x^3+5
Find f(7) and g(-3)
Simplify your answers as much as possible.
f(7)
g(-3)
To find f(7), we substitute x = 7 into the function f(x) = -5x + 2:
f(7) = -5(7) + 2
= -35 + 2
= -33
Therefore, f(7) = -33.
To find g(-3), we substitute x = -3 into the function g(x) = 3x^3 + 5:
g(-3) = 3(-3)^3 + 5
= 3(-27) + 5
= -81 + 5
= -76
Therefore, g(-3) = -76.
