Answer:
The value of the function f(x) at x=a can be determined by substituting a instead of x into the function expression.
1. When x=-1, then
f(-1) = 2 * (-1)^3 - 3 * (-1)^2 + 7 = -2 - 3 + 7 = 2.
2. When x=1, then
f(1) = 2 * 1^3 - 3 * 1^2 + 7 = 2 - 3 + 7 = 6.
3. When x=2, then
f(-1) = 2 * 2^3 - 3 * 2^2 + 7 = 16 - 12 + 7 = 11.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Since this is a right triangle, use the Pythagorean Theorem to find c.
Pythagorean Theorem ⇒ a² + b² = c², where a and b are the legs and c is the hypotenuse.
Plug in 10 and 24 for the legs and c for the hypotenuse.
10² + 24² = c²
100 + 576 = 676
√676 = 26
c = 26
