Compute f(-3) when f(x) = -4x^2 + 1

f(-3) = -35

Step-by-step explanation:

First, in this equation, wherever there is an x it will be replaced with -3. This means the equation would look like this: .

Second, you would do the exponent (-3 * -3 = 9) making the equation simplified to -4 * 9 +1.

Third, you would multiply from left to right (-4 * 9 = -36) making the equation be simplified to -36 +1.

Finally, you would combine these two terms together. This would your -35.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
