Step-by-step explanation:
f(x) = 3x⁴ - 5x² + 2x - 3
When x = -1,
f(-1) = 3(-1)⁴ - 5(-1)² + 2(-1) - 3 = 3 - 5 - 2 - 3 = -7.
Answer: y = (1/4)x - 1
Slope intercept form is . The -intercept is -1 so we have . To find , look at the points and . The line goes up 1 and over 4, so the slope, , equals . Thus the full equation is
.
Answer:
2 sec (θ ) − 2 tan ( θ )
Ox>5
x is less than 5
means nothing more than 5 but anything less than 5
