X=2
f(x)=4^2x-100
f(2)=4^2(2)-100
f(2)=4^4-100
f(2)=256-100
f(2)=156===> Answer
It’s 4, because ththey go by fours because of the way they go up.
Answer:
To find the x-intercept, make y equal to zero, and solve for x. To find the y-intercept, make x equal to zero, and solve for y.
Explanation:
<span>y=4x−2</span>
<span>
</span>
X-Intercept
<span>0=4x−2</span>
<span>
</span>
Add 2 to both sides of the equation.
<span>2=4x</span>
<span>
</span>
Divide both sides by 4.
<span><span>2/4</span>=x</span>
<span>
</span>
Simplify.
<span><span>1/2</span>=x</span>
<span>
</span>
Switch sides.
<span>x=<span>1/2</span></span>
<span><span>
</span></span>
Y-Intercept
<span>y=4<span>(0)</span>−2</span>
<span>y=−2</span>
