It’s D it’s substitution just not simplified
Answer:
y= 2x² + 2x +3
Step-by-step explanation:
y=f(x)
y=2( x^2 + 1^2 +2(x)(1) ) + 3
y=2x^2 + 1 + 2x +3
y= 2x^2 + 2x +3
The photo show how to solve the equation. Also you can use calculator to solve the problem. The easiest way of doing this is using a scientific calculator then use shift solve method for the ans
Answer:
h(0) = -4
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
h(x) = -3x -4
h(0) = -3·0 -4 = 0 -4
h(0) = -4
_____
<em>Additional comment</em>
In general, a polynomial function evaluated when the variable is zero will have the value of any added constant. All of the variable terms will be zero. Since the constant in this function is -4, we know immediately that h(0) = -4.
