First, remove parenthesis.

$7i4i$

Secondly, multiple by the numbers.

$7*4=28$

$-28ii$

Third, apply exponents rule.

$-28i^2$

$i^2=-1$

$-28(-1)$

Finally, refine.

$=28\\$

Find the x-values for which f(x) = g(x) if you know that f(x) = x2 and g(x) = 9.

Juli2301 [7.4K]

Answer:

For the values of x = 3 and x = -3 the given functions f(x) = g(x)

Step-by-step explanation:

Here, the given functions are

$f(x) = x^{2} \\g(x) = 9$

Now, given f(x) = g(x)

⇒ $x^{2} = 9$

or, $x = \sqrt{9} \implies x = 3, -3$

Hence, for the values of x = 3 and x = -3 the given functions f(x) = g(x)
