Question

Дана функция f(x)=7x^2. Вычисли f(-1)=

Answer 1

Відповідь:

7

Покрокове пояснення:

f(-1)=7*(-1)^2=7

Answer 2

To compute the value of the function $f(x) = 7x^2$ at $x = -1$, you simply need to substitute $-1$ for $x$ in the expression and calculate the result:

$f(-1) = 7(-1)^2$

Now, let's simplify it:

$f(-1) = 7 \cdot 1$

$f(-1) = 7$

So, $f(-1) = 7$.
