Answer:

The value of f(-1) is 21

Step-by-step explanation:

Given:

f(x) = 3x^5 - 5x^4 + 29

Finding f(-1)

        f(-1)=3(-1)^5-5(-1)^4+29\\\\

Multiplying '-1' odd times gives -1 and even times gives '1'

       f(-1)=3(-1)-5(1)+29\\\\f(-1)=-3-5+29\\\\f(-1)=-8+29\\\\f(-1)=21\\

The value of f(-1) is 21

write the equation that describes the line in slope-intercept form. slope = 4, point (3, −2) is on the line y = 4x 14 y = 4x − 2
amid [387]
Equation of a line is given by y - y1 = m(x - x1) where m is the slope and (x1, y1) is any point on the line.

y - (-2) = 4(x - 3)
y + 2 = 4x - 12
y = 4x - 12 - 2
y = 4x - 14
