Y = 0.08x2-1.6x+13 and y = 0.08(x-10)2<span>+5 is the correct answer :)</span>
Answer:
The functional expression can be simplified by substituting the given value in the function in place of the variable.
For example, if {eq}f(x)=x^{2} {/eq} be a function then {eq}f(2) {/eq} is determined by plugging {eq}x=2 {/eq} in the function.
Step-by-step explanation:
The given function is:
{eq}f(x) = 4x^{2} + 2x {/eq}
Let {eq}y=\frac{f(x + h) - f(x)}{h} {/eq} then we have:
{eq}\\\\\begin{align*} y & = \frac{4(x+h)^{2} + 2(x+h)-(4x^{2}+2x)}{h} \\\\ & = \frac{4(x+h)^{2} + 2(x+h)-(4x^{2}+2x)}{h} \\\\ & = \frac{4(x^{2}+2xh+h^{2}) + 2x+2h-4x^{2}-2x}{h} \\\\ & = \frac{4x^{2}+8xh+4h^{2}+ 2h-4x^{2}}{h} \\\\ & = \frac{8xh+4h^{2}+ 2h}{h} \\\\ & = \frac{h(8x+4h+2)}{h} \\\\ & = 8x+4h+2 \\\\\end{align*} {/eq}
Answer:
False
Step-by-step explanation:
Repeating decimals occur or results when there is a remainder from the division and further division will still take place.
<span>Yes, the equation can be solved by factoring. Using the given equation, take the square root of both sides. Both 169 and 9 are perfect squares, so the left side becomes plus or minus 13/3, which is rational. Six plus 13/3 is a rational number, and 6 minus 13/3 is also a rational number. If the solutions of a quadratic equation are rational, then the equation is factorable. </span>
