Answer:
first thing you gotta do is substitute x with -1 then you do the work first you gotta know your order of operation which is PEMDAS what that stands for is perentice exponent multiplication division addition and subtraction so then what you do first is 2*-1+3 2*-1=-2+3=1 and that is the answer you are WELCOME.
Step-by-step explanation:
He starts at a speed of 4 fps.
He adds 2 fps of speed during each of 3 seconds, for a gain of 6 fps.
At the end of the 3 sec, his speed is (4 + 6) = 10 fps.
We know nothing about the direction in which he runs, so we're in no position to discuss velocity. The best we can do is to determine his final speed.
To find the value of y in the given equation, substitute the given value of x to the equation.
y = 4x + 2x² -x³
Substitute 2 for all x's.
y = 4(2) + 2(2²) - 2³ = 8
Therefore, the value of y is 8.
